Save-tan has recorded the following tropes in use on RHA:
- Ascended Extra:
- Naru Osaka goes from being Usagi's out-of-the-know friend and Plot Magnet, where here it means Monster Magnet; to an information specialist, researcher, and cross-theme connector. And still a notorious Monster Magnet.
- Takashi/Riventon is one of the most well known OCs (possibly more well known than many of the CCs on the mush) and makes a re-appearance in the new mush. His story is different this time, as he is the found-family of Mamoru Chiba and mentor to Hotaru Tomoe, both of who started as 'villains'.
- Chrono Harlaown, the enforcer from Nanoha who mostly serves the role of 'Shows up and helps move plot along so Nanoha and Fate can blast things' in Magical Girl Lyrical Nanoha. Was far more popular than his player ever expected.
- Coco from Mermaid Melody Pichi Pichi Pitch, who had only appeared in 12 episodes out of 91 and received an extensive role in 4 of them and had only existed to provide exposition about Sara and be a Plucky Comic Relief.
- Ascended Fangirl: Amanda Faust; The parallels between herself and the fictional La Pucelle of Magical Girl Raising Project do not escape her. Although, far more than Magical Girl, she's a fan of Gender Bender... and Transformation Fiction, resulting in her being horrified whenever Akumatized friends turn bystanders into inanimate objects.
- Badass Adorable: Fate, Nanoha, Firefly(Hotaru/Mistress 9), La Crima, the list of badass and adorable characters is endless.
- Badass Bookworm: Cho Konishi, member of the Student Council regular achiever of great grades, and a tutor other students; she punches well above her weight class as the resilient and adaptive Cure Wukong.
- Balance Buff:
- Coco has received one to get her more involved in battles, having previously had a single move with various supportive applications.
- Wako Agemaki, whose abilities in Star Driver were limited to defensive shields and being a Barrier Maiden, has developed an assortment of offense applications of her powers.
- Crossover Couple:
- Takashi Agera and Mami Tomoe
- Hinoiri Kirara and Sayaka Miki.
- Naru Osaka and Adrien Agreste.
- Expy:
- Hinoiri Kirara, a pre-redemption version of Sunset Shimmer. She believes she's a unicorn from a place called Kirakirafantastica. Uses a lot of fire magic.
- Niji Dasshu, a version of Rainbow Dash. Has joined up with pretty much EVERY team sport club and while she's not the best at any of them (blame it on magical girls in general being amazing), she tends to be the best volleyball player on the football team, the best football player on the baseball team, the best... rinse, repeat.
- Rubi, based on Ruby from RWBY.
- Ryoko Gushiken, Cinder Fall from RWBY and a new villain of Obsidian.
- Inevitable Mutual Betrayal: The entire basis for Hinoiri (Sunset Shimmer expy from EQG) and Double Trouble (from SPOP) being roommates. They're both certain that they're playing the other person and even openly expect the other to betray them.
- Fountain of Youth: The formerly 36-years-old Amanda Faust discovered that Wake Up, Go to School & Save the World is in fact a package deal after making a contract with Kyubey to become a Magical Girl. But it turns out that merely existing for a couple of decades longer than her peers did not better prepare her for the trials and tribulations of being a teenage girl... or fighting deadly magical monsters, for that matter!
- Gender Bender: Amanda Faust treated this trope's page as a reading list and then went even further beyond. Now she finds herself living it, and cannot help but see the resulting situations in terms of the tropes of the genre. Although she realized she's Transgender a couple of months in, Amanda still feels the influence of decades of stories keenly, and would even if she weren't also isolated from others by involvement in magic and the peculiarities of her situation...
- Instant Costume Change:
- Amanda Faust can magically wear new clothes on the fly.
- Veronica Perenna can create disguises of general and specific people with her magic.
- The Inner Senshi's Disguise Pen (property of Usagi) allows one to assume certain roles.
- Jerk with a Heart of Gold: The Lead Engineer fairy beaver Enji towards his protegee Miya Sakamoto, who doesn't hesitate in using abusive discipline despite deep down caring about her.
- Literal Split Personality: What happened to Sayaka Miki after trying to secure a Lost Logia known as the Scroll of Ka. One half, who has kept her more upbeat and determined personality traits, has assumed her legal identity, while the other, who instead has retained her self-esteem issues and inflexible personality, has taken on the identity of Klarissa Miki, her previously unknown twin sister. The reserving of negative personality traits to entirely one half isn't a coincidence, as that's the purpose of the Scroll of Ka: forcing the two different halves to reach common grounds in order to rejoin so the person may get back better.
- Magic Idol Singer: Coco's defining trait as a magical girl.
- More than Mind Control: The default of Mamoru Chiba/Tuxedo Kamen on this Mush, who has taken the villanous identity of Darien Shields/Hematite due to an infusion of Dark Energy around his still pure Heart Crystal ever since the Mush equivalent of the Episode/Volume 1 of Sailor Moon.
- Named by the Adaptation: Coco from Mermaid Melody Pichi Pichi Pitch received the surname Kiumi when she leveraged her kingdom's influence to get herself in as an official guest at the Masquerade Ball of Princess Dia.
- Nebulous Evil Organisation: Obsidian, the business housing all of the villains. Most of them believe that, one day, they will stand tall above all... Fortunately, there's so much infighting that they rarely actually succeed.
- Spontaneous Choreography: Hinoiri, the villainous Sunset Shimmer expy, is used to people breaking into songs randomly. This... is not something that most understand. Sometimes people go along with it... usually, they don't.
- The Engineer: Miya Sakamoto/Cure Spanner is this as part of her magical girl theme and pursues this activity even in her mundane identity.
- Wreathed in Flames: Sunbreaker wreathes her body in black flames that have done quite a bit of damage, both physically and psychologically.
