Kisshouharukaze High School
Kenji Matsudaira
Kenji Matsudaira
Voiced by: Tatsuhisa Suzuki
Koutarou's Best Friend.
- Big Brother Instinct: Towards his little sister Kotori. This waffles between My Sister Is Off-Limits and worrying that she is too shy. He wants Koutarou to "take responsibility" for her as a result.
- Bromantic Foil: He serves as the harem protagonist's Best Friend and Foil. Unlike most examples, he is fairly popular on his own right, but unfortunately for him, the women he is most attracted to are all attracted to Koutarou instead.
- The Charmer: Known for his good looks and is the usual romantic lead for the drama club.
- Chick Magnet: He's known (infamously) as a ladykiller, attracting more ladies than Koutarou. This seriously distresses Kotori when she finds out.
- Childhood Friends: With Koutarou. They went to elementary school together.
- Informed Attractiveness: He's mentioned to be good-looking enough to pass off as a professional actor. Although, in a series where everyone is good-looking, he doesn't look especially handsome.
- In-Series Nickname: "McKenzie" (Matsudaira Kenji)
- Locked Out of the Loop: Realizes how close Koutarou is getting to the Invaders but knows nothing of what is happening behind the scenes. Finds out spectacularly in Volume 30 when he and Kotori are with Nalfa Laren when Ralgwin's men attempt to assassinate her. Watching Koutarou single-handedly stand off 40 armed attackers, then take down the mobile weapons they left for covering fire with help from Ruth, Sanae, and Shizuka is a major revelation. Nalfa's fangirling helps sell it.
- Unwitting Muggle Friend: He's the only completely normal person in Koutarou's life and he has no idea of what goes on at Corona House, especially the crazy stuff his best friend is involved in.
- Vitriolic Best Buds: His friendly banter with Koutarou is fairly constant.
Kotori Matsudaira
Kotori Matsudaira
Kenji's little sister. Is only alluded to for most of the series, but starts getting more focus after she enters highschool in book 30, becoming Nalfa's Best Friend.
- Honorary True Companion: After she and Nalfa move next door to Room 106, the group start casually including them in meetings. Lampshaded by Kotori, who says they shouldn't be talking about top-secret information in front of civilians, and makes them promise to discuss the really important stuff in private.
- In-Series Nickname: "Kin-chan" (Kin being an Alternate Character Reading of her name), or "McKinley" to go with her brother's.
- Locked Out of the Loop: Like Kenji, knows nothing about goings on in Room 106 for the first 31 volumes.
- "Kou-niisan is ... It's like that play came true...", Volume 30. Exactly.
Cosplay Club
The Cosplay Club
The cosplay club that Yurika and Maki are part of.
- Cosplay Otaku Girl: They're a club of girls who are passionate about cosplay.
Drama Club
The Drama Club
The Drama Club whose contest to develop and produce a play lead Theia to write the first Blue Knight Play- Life Imitates Art: In universe, Theia's rendition of The Silver Princess and the Blue Knight, Part 1 sets the stage for the romantic lead, played by Koutarou, to travel back in time to become the historical Blue Knight. Further, it appears that most of the major characters in the play were portrayed by members of the Corona House crew who were the synchronicities of the historical personages they played. Most notably, Harumi, the actual reincarnation of the Silver Princess, and Theia, the descendant of Princess Charl.
Unpopular Boys Alliance
The Unpopular Boys Alliance
A group consisting of 8 boys (with Koutarou as the leader) that are not popular with the ladies.- Mostly just mentioned in passing, the "Alliance" breaks up at the end of Volume 9, when an attempt to prank Koutarou with fake Valentine's Day chocolates find them instead watching as he receives chocolates from most of the Invaders. Afterwards, they occasionally stare at him sullenly when he's chatting up the girls.
Shiori Kashiwagi
Shiori Kashiwagi
A shy girl who knew Koutarou in elementary school, and confesses to him in book 23.
- First Girl Wins: Averted, but in Volume 29, in the Alternate Universe where Koutarou never met the invaders, Shiori became the person to "open the wall around his heart".
- Girlish Pigtails: Wears her hair like this.
Other

Takami Satomi
Takami Satomi
Koutarou's deceased mother.- Deceased Parents Are the Best: Takami is really loved by her family, so much so that after she died her family temporarily collapsed.
- Missing Mom: She died in a traffic accident, causing a trauma for her son.
- Small Role, Big Impact: Her death is the source of Koutarou's flaw that's also the invaders' biggest obstacle.

The Sun Rangers
Sun Rangers
Voiced by: Atsushi Tamaru (Red), Tooru Sakurai (Blue), Rena Maeda (Pink), Ayumu Murase (Green), Kouji Seki (Yellow), Yoku Shioya (Dr. Roppongi)
Taiyou Butai: Sunranger!
A Sentai unit created by the Japanese government to battle evil-dwellers who lurk Beneath the Earth, consisting of Kenichi (Red Shine), Hayato (Blue Shine), Megumi (Pink Shine), Kotarou (Green Shine), Daisaku (Yellow Shine) and their sponsor Dr. Roppongi. Their technology was actually leaked to them by the People of the Earth's conservative faction in order to put pressure on those who wish to invade the surface. Initially gag characters, they grow over time into real heroes who command the respect of others.
- A Day in the Limelight: An off-duty Daisaku appears in book 27 to compete against the protagonists in an eating contest. Koutarou is disappointed that it couldn't be the The Leader who challenged them instead.
- Cassandra Truth: Early in the series the team struggles to secure funding, as their superiors have serious doubts about whether the enemies they're preparing for even exist. By their second appearance this has been resolved, as underworlder radicals had become active enough for the team to prove their worth off-screen.
- Color-Coded Characters: Parodied in their first appearance, where due to budget constraints the team consists of five "Red Shines". Koutarou (playing the villain of the stage show they'd mistakenly interrupted) is actually offended that they'd put so little effort into the whole hero thing.
- Combining Mecha: The team is mentioned to have one in development in book 35, though it's proving a difficult enough engineering challenge that only the Sun Diver (which forms the legs) has been completed so far.
- Cool Boat: The team's submarine, the Sun Diver, introduced in Book 35. It unfortunately doesn't survive the volume, as they're forced to use its Self-Destruct Mechanism to destroy Ralgwin's escape route.
- Hero Worship: Towards "Baron Demon" (Koutarou) for helping them kick their team into shape, to the point of considering him an honorary Sixth Ranger. This only increases when they see him charge into battle with his own team of mysterious warriors behind him.
- Honorary True Companion: While their position as government agents means they can't be entirely in the loop, they also have great respect for the Satomi Knights and know when to keep their mouths shut. After Forthorthian delegates start arriving on Earth, the Sun Rangers and the Satomi Knights find themselves increasingly working together.
- Ideal Hero: The Sun Rangers are committed to "fighting like true heroes", using nonlethal attacks and trying to be good examples for children.
- Martial Arts Headband: Kenichi is usually seen wearing one, reflecting his Hot-Blooded status.
- Office Romance: Daisaku and Megumi eventually start dating.
- One-Steve Limit: Green Shine's real name is Kotarou, extremely similar to that of the protagonist Koutarou.
- Reassignment Backfire: As a department of the Japanese government tasked with dealing with aliens and similar threats, they were initially considered a joke. Then actual aliens make First Contact with Japan in book 27, causing their importance to balloon overnight.
- Scarf of Asskicking: In their civilian outfits, each of the team wear one in their signature colour.
- Super-Strength: Their spiritual-power suits quintuple the wearer's strength.
- Team Spirit: After some teething difficulties, they grow into an incredibly well-oiled team - Harumi claims that she could probably defeat any of them individually, but together they're unbeatable.
- Teeth-Clenched Teamwork: Surprisingly averted when the Sun Rangers receive contact from members of the People of the Earth, who explain that they're from a conservative faction which doesn't wish to invade the surface. Not only do the Sun Rangers accept them as allies almost instantly, they're actually relieved that the People of the Earth can be reasoned with and they won't have to fight a war of extermination.
- Took a Level in Badass: While first introduced as incompetent (to the point where their rolecall consists of the the entire team introducing themselves as "Red Shine"), by their second appearance they've undergone serious training to improve their teamwork and fighting ability. By their third appearance Koutarou claims that each member is likely stronger than he is.
- Trademark Favorite Food: Fitting the Sentai Yellow cliché, Daisaku loves eating curry.
The Ghost Hunters
Hachi + ???
Voiced by: Takaya Kuroda (older brother) and Tarou Masuoka (younger brother)
Suspicious? Don't be silly, can't you see their coats?
A pair of ghostbusting brothers who appear in book 3, where they plot a Get-Rich-Quick Scheme to kidnap and sell Sanae.- The Bus Came Back: After being hired by Kiriha in Volume 3, they come back in Volume 11 where it was revealed they've been monitoring Sanae's human body.
- Cut Lex Luthor a Check: When the hunters explain that they planned to sell Sanae for 300 million yen, Kiriha cuts off any future threat from the duo by simply buying Sanae herself at that price (on the condition that they share all the information they'd gathered on her). Book 11 reveals that this is when Kiriha learned of the living Sanae's existence, and employed the hunters to keep monitoring her.
- Depleted Phlebotinum Shells: Their tools include bug nets which can snare ghosts, and smoke bombs which block their Aura Vision (described as being created from the branches of sacred trees). Most of them appear to be things they've purchased from niche companies rather than created themselves.
- Fat and Skinny: The younger brother (Hachi) is short and fat, the unnamed older brother is tall and skinny.
- Mistaken for Pedophile: While trying to kidnap Sanae, they get Theia instead. The girls then think they're trying to kidnap little girls, when they're actually ghost hunters.
- No Name Given: The older brother is only ever addressed as aniki ("big bro").
- Sibling Team: A pair of brothers who run their business together.
- Sinister Shades: Less sinister, more suspicious.
- Who You Gonna Call?: Describe themselves as professional bounty hunters who specialise in capturing ghosts.
Ghost Woman
Voiced by: Fumi Morisawa
One of the twenty-or-so evil spirits employed by the ghost hunters in book 3, described as a long-haired woman in a hostess dress.
- Arc Villain: She's the villain of book 3. Later on, she returns in book 11.
- Bishōnen Line: When her giant form briefly absorbs Sanae it becomes opaque and gains a more human shape.
- Fusion Dance: She can fuse with other evil spirits to grow into a larger monstrous form.
- Mook Promotion: Introduced as one of the ghost hunters' minions, but hijacks their plans by trying to absorb Sanae.
- No Name Given: It's unknown what name she had when alive.
- Not Quite Dead: After her apparent destruction she manages to cling on to existence through The Power of Hate, returning in book 11 to attack Sanae a second time.
- Wake-Up Call Boss: The first genuinely evil antagonist in the series, who almost kills one of the protagonists and helps forge the first link in their True Companions fellowship.
Alexei Belachev
Alexei Belachev
A spy from the struggling Melgaard Republic who appears in book 28. After Forthorthian ambassadors make First Contact with Earth, he is among the legions of agents scrambling to get their hands on alien technology. When he hears reports of a School Play with a land named "Forthorthe" as its setting, he travels to Kisshouharukaze to investigate its author Theiamillis.- Anti-Villain: Has no evil intentions behind his actions, simply wanting a better life for his wife and son. The protagonists sympathise greatly with his situation, but don't want to risk leaking Forthorthian weapon technology or the existence of the (currently vulnerable) People of the Earth.
- One-Winged Angel: After the protagonists convince him he was on a wild goose chase, his despair somehow summons the Whirlpool of Chaos, causing him to first enlarge in size, then transform into a humanoid dragon as he is influenced by the remnants of Vandarion's mind.
