Characters / Classicaloid

Humans

Kanae Otowa

Voiced by Mikako Komatsu

The main protagonist and current homeowner/landlady of the Otowa mansion after her grandmother left it for her.

• A-Cup Angst: Worries about her bust size in episode 2. Her friend tells her it makes her swim faster but ends up incurring her jealousy when she shows off her breasts. The issue comes to a climax when Motes presents her with a breast-shaped cake, causing her to give him a Bitch Slap.
  • Played for a quick gag in episode 8, where she becomes self-conscious of her flat chest while trying on swimwear and gets offended when Liszt, Bada and Tchaiko tell her to change out of it.
• Character Development: She initially starts out as extremely strict and inflexible, and was afraid of what people would think of her if she was seen with the mischievous Classicaloids. Slowly she begins to loosen up around them, even growing fond of them, and no longer cares if they cause any trouble for her.
• Cheerful Child: Flashbacks in episode 1 show us that she used to be cheerful and carefree as a young girl. A photograph also depicts her smiling broadly with her parents.
• Cranky Landlord: A rare and benevolent case of a main character fitting this trope. Befitting her status of Only Sane Man, she's very strict about the Classicaloids breaking the house rules (not that they listen anyways), and threatens to kick them out when she's really pissed.
• Expository Hairstyle Change: As a child, she had long hair befitting her then-Ojou status. She has shorter hair now, indicating that she's matured quite a bit since then.
• Hair-Trigger Temper: According to Sousuke, she's scary when angered. Indeed, she often yells at the Classicaloids out of frustration with their antics. She also can get physically violent on occasion, with Sousuke and Motes usually on the receiving end.
  • By episode 11, everybody else in the mansion has come to fear enraging her.
• Improbable Age: She's in her first year at high school, living by herself, and renting out rooms to strangers in a house that she owns. Go figure.
• Meaningful Name: "Oto" means "sound" in Japanese, while her first name involves the kanji for "song".
• Missing Mom: Her mother left her father as a result of him wasting his inheritance and racking up debt.
• Only Sane Man: Usually takes this role while having to deal with the Classicaloids and Sousuke. When it comes to prospective tenants, she is more often than not this trope.

Sousuke Kagura

Voiced by Nobunaga Shimazaki

Kanae's Childhood Friend and freeloader at the mansion. A budding musician who idolises the Classicaloids' Musik.

• A Day in the Limelight: Episode 15 focuses on his attempts to make a band for the school festival with...mixed results.
• Butt-Monkey: If any slapstick is about to happen, there's a good chance he's going to be the victim. For a good example of this, look no further than the time he got turned into a "wrecking ball" in episode 2.
• Comically Missing the Point: He has a tendency to do this, complete with overreaction. For example, in episode 1:
  Beethes: "I feel something coming."
  Sosuke: "Are you serious? Do it in the bathroom!"
• Fanboy: Of Clasky:Klasky.
• Giftedly Bad: Schubert found his electronic music so dreadful that he started crying. Sousuke's left none the wiser about it and keeps on talking excitedly about his music.
  • Taken to its extreme in Episode 15 where his digital music causes glass to crack and objects fall down around him. His singing is even worse as it causes everyone in the school to collapse in pain. Beethoven even wonders if they're being assaulted by Musik.
• Malicious Misnaming: Often on the receiving end from Liszt's use of the trope. This comes to a head when the real Sousuke is replaced by a "MitsuruLoid".
  Liszt, about the MitsuruLoid: Piece of Junk really is a piece of junk, after all.
• Meaningful Name: One kanji of his surname, when paired with the "Oto" of "Otowa", becomes "ongaku" or "music" in Japanese. (Oddly enough, the other means "god".) His first name involves the kanji for "to play/perform (with a musical instrument)". Kagura is a certain type of ceremonial dance and music in Shinto.
• Online Alias: His screen name for online gaming is the somewhat embarrassing "Crying Dark Angel".
• Paper-Thin Disguise: He wears a couple of flimsy disguises (two of them involve merely wearing a girl's wig) throughout episode 8. The most elaborate one so far is when he wears sunglasses and a fake moustache to be a nondescript waiter on Liszt's rented boat. None of the girls recognise him until he purposefully breaks the act.
• "The Reason You Suck" Speech: He gives Bach a well-deserved one in episode 8 on his mistreatment of Tchaiko and Bada. However, when he finds out Bach's true identity, he freaks out and backpedals.
• Small Name, Big Ego: For an aspiring musician, he sure has a high opinion of himself. For instance, he brags to Kanae about using "DTM" (desktop/computer music) but all of the eight views he has on a video about him singing along to DTM are from him.
• Stalker without a Crush: He secretly follows the girls around on their day out, presumably because he's a fan of Tchaiko's and Bada's idol personas and wanted to meet them. He manages to avoid being seen and/or recognised by them for the majority of the episode until he chooses to out himself.

Composers (the titular Classicaloids)

Tropes that apply to all of them:

• Artificial Human: All of them were created in a lab by Kyougo Otowa. They were originally called "Alcheloids" before Bach redubbed them Classicaloids.
• De-power: Towards the end of Season 2, Wagner manages to successfully steal all nine of the other Classicaloid's Musik leaving him the only Musik wielder.
• Reincarnation: The personalities of the original composers are reborn into artificial bodies as part of Arkhe’s plan. However, the process proved to be imperfect, as several of them have notable differences. Whether it be changes in gender (Liszt and Tchaiko), skin color (Bach), age (Tchaiko and Wagner) or even species (Dvořák). Only Tchaiko appears to be bothered by it as she can't drink vodka due to being under aged.
• Magic Music: All of them have access to their "Musik", which reality warping power channelled through the playing of their original songs, complete with Magical Girl like transformations.
• Past-Life Memories: The Classicaloids appear to retain some memories from their previous lives, which they would occasionally make reference to (eg. Beethoven remembering a meeting with a young Liszt). Some of the more traumatic ones tend to inform some of their current characterisation (eg. Schubert’s hatred of Mozart came from people constantly comparing their music), or can even be Played for Drama (eg. Mozart mourning his mother’s death).

Ludwig van Beethoven

Voiced by Tomokazu Sugita

The so-claimed famous composer, Beethoven is one of the first composers to appear alongside Mozart, claiming to be friends of Kanae's father. Nicknamed "Beethes" ("Beto" to Japanese audiences).

• Berserk Button: Depriving him of the opportunity to taste his gyoza, as evidenced by him unleashing his Musik in episode 1.
• Determinator:
  • He strives to perfect his gyoza-making skills no matter what it takes! He goes through several intensive frying methods (at one point reducing the meat into ashes) as well as trying an array of black-coloured foods in order to achieve the recipe for what he terms as the 'Jet-Black Harmony Gyoza' in episode 5. He's trying to recreate the taste of the gyoza Kyougo had given to him. In episode 13, he's interested in fishing, but he uses gyoza as fish bait.
  • He is so intent on wanting to play the guitar that he shuts himself away in his room for weeks just trying to handcraft wooden guitars from scratch.
• Fleeting Passionate Hobbies: He has a one-track mind and tends to get obsessed easily. This is evidenced in episode 9, where he gains a new fixation on guitars; when asked about gyoza, he answers, "Gyoza? What is that?"
• Hot-Blooded: Comes with the Large Ham territory. You can't deny that the man has a lot of passion for everything that he does. Case in point: his room has pieces of paper taped to the walls that say "Gyoza is willpower!".
• Heterosexual Life-Partners: He and Mozart have shades of this, considering their Red Oni, Blue Oni dynamic and how they're rarely seen apart. They's also on a First-Name Basis, with their own nicknames for each other ("Wolf" and "Lud-kun") while everyone else calls them "Beethes" and "Motz".
  • As of season 2 they even share a room, Mozart having been forced to move out of his room when Wagner moved in.
• Large Ham: He often waxes lyrical about gyoza and/or fate.
• Messy Hair: He's rather eccentric and has wild Einstein-like hair.
• Playing with Fire: He seems to favour using flamethrowers - he uses them to cook gyoza and incorporates one into his guitar's final design.
• Red Oni, Blue Oni: Considered the blue to Mozart's red, he's quite straight-faced and serious whenever he isn't hamming it up.
• Trademark Favorite Food: Gyoza. He loves making it, vocally defending it and eating it, to the point where Motes' Eine Kleine Nachtmusik (which has lyrics about making wishes come true) gives Beethes a gyoza suit and dancing gyoza buddies. It's also integral to his character development, too - Kanae's father had made some unusual sweet gyoza with a black filling to cheer him and Motes up.
• Transforming Mecha: His initial Musik shtick is to create these.
• The Unapologetic: He's proud, stubborn and cocksure in his actions that he never repents or apologises for anything. This makes him immune to the effects of Motes' Requiem in episode 7, allowing him to give Motes a much-needed punch on the head. Kanae calls out Beethes for this, saying that he has loads to repent for.

Wolfgang Amadeus Mozart

Voiced by Yūki Kaji

One of the first composers to appear alongside Beethoven. Nicknamed "Motes".

• Casanova Wannabe: He loves the ladies but hasn't actually been in a relationship on-screen yet. Still he flirts with Kanae and calls her hot, and goes out with Sosuke to the festival in episode 3 in order to meet girls.
  • While he does have an Estrogen Brigade in Kanae's friends after he impresses them with Musik in episode 2, he rarely has a chance to interact with them afterwards.
• Heterosexual Life-Partners: He and Beethoven have shades of this, considering their Red Oni, Blue Oni dynamic and how they're rarely seen apart. They're also on a First-Name Basis, given that he refers to him as "Lud-kun" and Beethes calls him "Wolf".
• Innocently Insensitive: Motes comes across as this sometimes.
• Keet: So energetic and playful that he chases a rat up a pole just to get back some black beans he'd bought for Beethes in ep 5.
• Laughing Mad: Occurs temporarily in episode 7, where he rains down repentance-inducing onto random civilians out of grief for the perceived death of a fawn he had been caring for.
• Long-Haired Pretty Boy: He sports a long braid, and his hair is shown to be very long when unbraided. He's also the most feminine-looking male character in the show, bordering on Bishōnen.
• Manchild: Frequently seen wheeling around on roller shoes despite looking a little too old for them. He's also rather immature and loves annoying others, especially Schubert.
• O.O.C. Is Serious Business: If he's not his happy, upbeat and active self, something is wrong.
• Parental Substitute: Became one to a baby deer in Episode 7 because he sympathized with its mother's death.
• Red Oni, Blue Oni: The red to Beethes' blue, he's the more outgoing and energetic of the two.
• Rollerblade Good: Has the childish personality for this and frequently uses this method of getting around.
  • The katakana version is actually "Motsu" due to the way "Mozart" is written in that writing system, but "Mot" and "Moz" don't sound like a derivation of "Mozart" in English.
• Toilet Humour: Passed down to him by his mother, his love of perverted and scatological humour is on par with that of his real life counterpart. Look no further than episode 2, where he makes a cake resembling breasts in order to impress Kanae.

Franz Liszt

Voiced by Mamiko Noto

Moves into the house in Episode 3. Nicknamed "Lisz-chan".

• Attention Whore: Downplayed. She doesn't demand that she be in the spotlight but she certainly enjoys the attention. She mentions in episode 3 that she loves giving live performances, which had temporarily blinded her to Chopin's fear of them. This is given more focus in episode 11, where she believes that she must become the symbol of feminine beauty at the Otowa mansion while Kanae is away. Instead of doing her given chores, she hams it up and strikes ridiculously dramatic poses in various places.
• Gender Flip: The real Liszt was a man. Lampshaded by Beethes, who recalls meeting Liszt as a young boy in his previous life.
  • In comparison to Tchaiko, Liszt doesn't really mind being a woman and even takes full advantage of it at times (eg. experiencing a girls' day out for herself). When being asked why she became a woman, she haughtily says "I don't know. Why does it matter?" and winks to the audience.
• Love Freak: She's really, really into the idea of love. She's able to sense the love present in the mansion, which motivates her into using Musik in episode 3. She even gets excited just thinking about it.
• Malicious Misnaming: Frequently calls Sousuke "tool" or "piece of junk", especially when she expects him to do something.
• No Sense of Personal Space: She's rather affectionate towards Kanae, and is often stroking her face and leaning closely to her while talking. Kanae herself is flustered by this, at one point telling Liszt to stop hugging her so much.
• Odd Couple: She's vain, attention-loving and extroverted but cares dearly for the shy and reclusive Chopin. She tries to get him out his comfort zone but to no avail. Notably, there is some historical basis to this.
• Parent Service: She's noticeably the curviest and most mature-looking woman in the anime, and provides quite a bit of fanservice.
• Victoria's Secret Compartment: Downplayed. She sometimes stashes documents in between her breasts, but it doesn't have much bearing on the plot.

Fryderyk Chopin

Voiced by Kosuke Toriumi

Moves in with Liszt in Episode 3. Nicknamed "Cho-chan".

• Deadpan Snarker: During times where he does bother to speak, he's usually this trope. It helps that he doesn't think very highly of people in general, especially the ones living in the mansion.
• Hikikomori: He isolates himself in his room with all the windows walled up. In his introductory episode, the people living in the Otowa mansion are mostly kept in the dark of his presence until Liszt shows up to bring him back to the agency. He's also fairly creepy in the eyes of others occasionally.
  • He inverts the trope for most of episode 16 due to a backpacker phase, only to discover Beethes and Motz in the countryside picking tea leaves.
• The Lost Lenore: "Jolly", whom is more historically known as his former girlfriend George Sand. He recreated the latter as a virtual idol due to his loneliness, and used Musik to make her more real - accidentally making her into a Classicaloid in the process. When Jolly willingly allows herself to be deleted, Chopin is shown to not have gotten over her death by attempting to create Jolly 2.0.
• Odd Couple: Despite his shy and reclusive nature, he is best friends with the more outgoing Liszt. He simply finds her the most tolerable out of the Otawa mansion residents, and usually follows her to most places. Notably, there is some historical basis to this.
• The Quiet One: He doesn't talk very much compared to the other Classicaloids living at the Otowa mansion, and is usually above their antics to some degree.
• Shrinking Violet: He seems to have social anxiety to some extent, to the point where he activated his Musik just to get away from the main cast. Curiously, he's a lot more social online.

Franz Schubert

Voiced by Tomoaki Maeno

Moves into the house in Episode 6. Nicknamed "Schu-san".

• Ain't Too Proud to Beg: After being turned into a trout in episode 13, Schubert is forced to beg Mozart to help him. Not that it works as Mozart can't understand him anymore.
• Cosmic Plaything: Heavily implied to be the case, since his Musik always goes wrong and he can't be with his Beethoven-senpai for too long lest there be a problem (either involving Musik or not).
• Determinator: Vowed to never stop looking for Beethoven until he found him, thus leading to him Walking the Earth. Once he stops Walking the Earth, he'll go to any length to please his senpai.
• Fish out of Temporal Water: Because he escaped from the facility shortly after awakening, he didn't initially realise he was in the modern day and struggled to adapt to it, more so than the other Classicaloids.
• Forced Transformation: He transforms people into fish and other aquatic wildlife with Die Forelle ^note The Trout. In the episode this is unveiled (episode 13), Schu-san becomes both a realistic trout and a more cartoon-like one.
• Inferiority Superiority Complex: Wagner points out that both of his Hip-Hop and Reggae personas were attempts to be more confident and hide his low self-esteem.
• Love at First Sight: Non-romantic version; upon looking out the window and seeing Beethoven in his flashback in Episode 3, he immediately began idolizing his "Beethoven-senpai."
• The Mind Is a Plaything of the Body: After being turned into a trout, he struggles to think complicated thoughts and can't stop thinking about food.
• Naked People Are Funny: Him waking up naked in the Classicaloid creation facility and idolising his senpai while said senpai escapes. This trope is also the reason why he doesn't have Magic Pants at the end of episode 13.
• Power Incontinence: He can't quite control his Musik powers, thus causing random bouts of infantilisation everywhere he goes in his debut episode.
  • It happens again in Episode 13 where he inadvertently uses his Musik via singing and turns into a trout for the majority of the episode.
  • By Episode 21 he's fully awakened his Musik and gained full control.
• Sitcom Arch-Nemesis: He absolutely loathes Mozart due to his music being ostracized when compared to Mozart's in his previous life.
• Stoic Spectacles: Is normally the most stoic of the group that bases itself at the Otowa mansion. He does have his Not So Stoic moments, however, such as when he fanboys over his senpai.
• Unknown Rival: He hates Mozart with a passion, who in turn seems to not even be more than acquainted with him.

Pyotr Ilyich Tchaikovsky

Voiced by Aya Endo

Nicknamed "Tchaiko-chan".

• Clingy Jealous Girl: Nearly assaults Kanae when she hears that Bach spent an afternoon with her.
• Idol Singer: Episode 2 shows her as one half of an idol group with Badarzewka called "Clasky:Klasky". However, she quits the group over creative differences with her partner following episode 14.
• Gender Flip: In real life, she was male.
• Swarm of Rats: Tchaiko's Mooks, led by her pet rat King.
• Translator Buddy: She is the only one who can understand Bach's use of musical terms out of Clasky:Klasky, and translates for the benefit of Badazewska, who can't quite understand him. However, she doesn't know what Bach's true intentions are since he doesn't give her any further information, which frustrates her. In episode 13, it's revealed she knows Bach can speak normally - it's just that he doesn't do so for some reason.
• Trademark Favorite Food: Wild mushrooms.
• You Dirty Rat!: Turns her rat King ^note  a reference to The Nutcracker, whose antagonist is the Rat King into a bucktoothed man to capture the Classicaloids.

Tekla Bądarzewska-Baranowska

Voiced by Mao Ichimichi

Nicknamed "Bada-chan".

• Berserk Button: Calling her a "one-hit wonder" is sure to enrage her.
• Green-Eyed Monster: She is secretly jealous of Tchaiko's talent in Musik, which leads to her constantly being overshadowed by the latter. This comes to a head when they break up in episode 14, as Bada sees this as her chance to step into the spotlight once more.
• Idol Singer: Episode 2 shows her as one half of an idol group with Tchaikovsky called "Clasky:Klasky". She remains with the group even after the departure of her partner from the group in episode 14, taking on Kanae as a replacement.
• Ship Tease: With Sousuke. She even gave him her personal email contact details in episode 12.
  • Season 2 also implies that she has a crush on Bach.

Johann Sebastian Bach

Voiced by Taiten Kusunoki

The Big Bad of Season 1.

• Affably Evil: He is quite polite and cordial to Kanae, even willing to listen to her opinions on the Classicaloids.
• Ambiguously Brown: The only Classicaloid to have this skin colour. This is somewhat baffling given that the original J. S. Bach was white and that the current Bach was created in a laboratory.
• Antagonist Abilities: Power Nullifier, Mind Manipulation and Powers Do the Fighting (via Guardian Entity).
• Bright Is Not Good: His composer costume and Musik incorporate mostly whites and golds, yet he is the main antagonist of the series.
• Busman's Vocabulary: He speaks near exclusively in musical terms when giving orders. The first time where he doesn't do this is in episode 6, where he simply utters "Classicaloid" to establish himself to his employers.
• The Comically Serious: Often plays this role when interacting with the sillier characters like Mozart and Kyougo.
• Cool Shades: A distinguishing characteristic of his composer outfit that is created during his Musik transformation.
  • Sinister Shades: He's the main antagonist of the series and his motives for capturing the rest of the Classicaloids aren't made entirely clear at first.
• De-power: In Season 2. After attempting to squash Wagner's revolution, he gets his Musik stolen and is forced to retreat.
• Heel–Face Turn: Convinced by Kanae that his methods will only hurt more people than save, and so he works together with the other Classicaloids to save the Earth in the final episode.
• Finger-Tenting: Initially he does a lot of this. Once he stops doing this, the plot really gets moving.
• Magic Staff: His baton in Composer form is more in the shape of a staff rather than the wand sized batons used by the other Classicaloids. This is a reference to conductors during Bach's time commonly using wooden staffs to beat out time instead of waving it.
• Mean Boss: For Tchaiko and Bada. He works them to exhaustion as part of their Clasky:Klasky idol act but they're too afraid of him to make a direct complaint.
• Older Is Better: Bach is the original Classicaloid and as a result, is leagues more powerful than the others.
• The Stoic: In his early appearances, he doesn't show any outward emotional reaction at all. Come episode 12 and this trope is subverted - he's actually more expressive outside of work.
• Terse Talker: He strings musical terms together as short, one-word sentences in quick successive order. Suffice to say, he isn't very verbose. Later averted.
• Well-Intentioned Extremist: He genuinely wants to protect humanity against the oncoming threat of the aliens. But his plan to turn all of humanity into Classicaloids would turn music into a tool rather than something to enjoy and share.

Richard Wagner

Voiced by Yoshitsugu Matsuoka

A new Classicaloid introduced in Season 2 and claims to be Kanae's long lost brother under the name "Wataru Otowa".

• Antagonist Abilities: Power Parasite and by extension - Power Nullifier, Mind Manipulation & Guardian Entity thanks to stealing Bach's Musik.
• Berserk Button: Don't call him blotched.
• Big Bad: Of Season 2. Cemented by him awakening to his Musik and stealing Bach's.
• Bitch in Sheep's Clothing: Acts nice in front of Kanae to win her trust, but secretly sabotages the other tenants in order to make them look bad. Liszt is the only one to see through it.
• Brutal Honesty: Bluntly tells Schubert that his attempts at Hip-Hop are forced and make him look terrible.
• Et Tu, Brute?: He feels betrayed upon seeing Dvořák preform a Heel–Face Turn and is living happily with the others at the Otowa Mansion.
• Flawed Prototype: He and Dvoak were to be the 9th and 10th Classicoids after the Ocatve in the orginal plan to mass produced them. However Wagner's Musik wouldn't activate and thus was a blotch.
• Malicious Misnaming: Repeatedly gets Sousuke's name wrong, much to the latter's annoyance.
• Paper-Thin Disguise: Infiltrates Bach's company by putting on a pair of sunglasses and calling himself "Producer Wataru". Both Tchaiko and Bada are completely fooled.
• Power Parasite: The true nature of his Musik. He manages to steal Bach's Musik and use it for himself.

Antonín Dvořák

Voiced by Jun'ichi Suwabe

A new Classicaloid introduced in Season 2, though seems to be a hippopotamus for reasons unknown. Called "Dovo-chan" by his so-called master Wataru.

• All Animals Are Domesticated: Justified due to his hidden sapience.
• The Mind Is a Plaything of the Body: Similarly to Schubert's Trout transformation, Dvořák retains his human intelligence but constantly has to battle against his "animal instincts" while in the hippo's body.
• Heel–Face Turn: Upon realising that Wagner has forgotten their promise whilst in the midst of conquering Arkhe, Dvořák defects and returns to the Otowa Mansion and assists the other Classicaloids.
• Motor Mouth: To Chopin's horror, his "silent companion" turns out to be extremely talkative once he is finally able to speak thanks to the power of Musik.
• Mythology Gag: His ability to communicate his thoughts through Musik is a callback to Bach's plan in season 1 to turn all of humanity into Classicaloids and unite them overcoming barriers of language and other miscommunication.
• Minion with an F in Evil: Unlike his master, Dvořák rarely does anything antagonistic towards the other characters and usually fails when he's ordered to do so. It's a large reason why he's quickly forgiven when he preforms a Heel–Face Turn.
• Paper-Thin Disguise: Wagner disguises him as a rhino called "Kuro-chan" by putting a plastic horn on Dvořák's head and everyone is fooled.
• Rail Enthusiast: Much like his historical counterpart, he loves trains. His Composer outfit even resembles a Train Conductor's uniform.
• Sapient Pet: He has retained his intelligence as a human, but masquerades as Wagner's pet in public - much to his annoyance.
• Suddenly Voiced: Once he activates his Musik he suddenly gains the ability to speak human language while otherwise not possessing the vocal chords to do so.
• Team Pet: Competes with Hasshie for this role.

Other Characters

Pad-kun

Voiced by Akira Ishida

Sousuke's robotic companion.

• Benevolent A.I.: He's very talkative and unique compared to a regular tablet. Unfortunately, he also screams in agony when he's forcibly shut off.
• Can't Stand Them, Can't Live Without Them: Despite his constant bickering with Sousuke, once he's forced to spend an entire day without him, he realises how much he misses Sousuke.
• Deadpan Snarker: Frequently sneaks in little "Yeah, yeah"s and such when obeying Sousuke's commands.
• Humanity Ensues: Downplayed, as he has an Anthropomorphic Personification of sorts (a blue-haired butler-looking Bishōnen with eye-covering bangs), but only in Cyberspace. Sousuke identifies the human Pad-kun like this:
  Bishōnen: What are you talking about, Sousuke? We were together until a moment ago, and you've already forgotten? (points to his head) Are you really that slow?
  Sousuke: That sarcastic way of speaking...Don't tell me you're Pad-kun?!
• Mr. Exposition: He provides information on the previous lives of the Classicaloid composers and the songs present in their Musik. Also takes on this role momentarily in episode 13 to identify the types of fish (and single snail) present in the pond, due to the fact fish can't understand human ways of communication.
• Sliding Scale of Robot Intelligence: Between levels 3 and 4, because while he does have feelings and sarcasm, the most intelligence he has shown beyond that is operating the functions of "The Searcher", the in-universe counterpart to Google.
• Straight Man: Plays this in regards to his goofy owner Sousuke.

Hashie

A blue shoebill that wears a green scarf.

• A Dog Named "Dog": Hashie is a shortening of hashibirou, the Japanese word for "shoebill".
• Ambiguous Gender:
  Motz, looking at Hasshie's chest and tail: Hasshie, are you a boy? Or are you a girl?
• Nearly Normal Animal: Strangely, aside from its involvement with Musikal activities, its color, its scarf and the rare human-like expression, it is a normal, albeit out of place, shoebill.
• Spectacular Spinning: Seems to enjoy riding the robot vacuum in episode 10, to the point where it doesn't complain about being spun rapidly on said robot vacuum due to Musik.
• The Stoic: Doesn't talk or emote much, except when it panics.
• The Voiceless: What do you expect from a shoebill?

Kanae's Grandmother

Kanae's deceased grandmother and previous owner of the house which the Classicaloids move into.

• Old Money: She comes from a distinguished noble lineage and was very wealthy in life.
• Posthumous Character: Kanae frequently and fondly remembers her though.

Kyougo Otowa

Kanae's father, a scientist and creator of the Classicaloids.

• Disappeared Dad: At the start of the series, he's away for unknown reasons. He makes contact with Kanae via hacking a video message onto Pad-kun in episode 5 but doesn't elaborate on what he's doing.
• Spanner in the Works: Awakening Beethoven and Mozart early and then helping them escape prevented Bach's initial plan.

Akira Mitsuru

The assistant of Kanae's father and current right hand woman to Bach.

• The Dragon: For Bach, to the point where she distributed the Arkhe Doll program that shot Jolie (and by extension, Cho-chan) to fame.
• Gender-Blender Name: "Mitsuru" is a male given name (discussed briefly in episode 18), while "Akira" is a gender-neutral name.
• Lady Looks Like a Dude: Can be mistaken to be a Bishōnen due to the Gender-Blender Name problem.
• Kick the Dog: She joins in on the second attempt to tear down the mansion, not caring that it's Kanae's home, or for her well-being had they succeeded in their task.
• Pet the Dog: When Beethoven and Mozart come to her for a job, she sets them up with legitimate interviews with a local school looking for music teachers with no strings attached.
• Sexy Secretary: It's unclear exactly how much Bach does and how much Mitsuru does since Bach is mostly shown sitting and Finger-Tenting at a desk, but for the most part she plays this role to Bach.
• Undying Loyalty: To her "Bach-sama".
