Seito Kaichou Hikaru/Characters

St. Maris Academy's Student Council

In General

The student council at St. Maris Academy, a school that trains its student to fight demons/youkai. They are stated to be the strongest among students, who actively defends their school from demons.

• Absurdly Powerful Student Council: Somewhat justified, considering the student council are Superhero demon slayers that protects their school from supernatural threats.
• Amazon Brigade: All the members of the Demon Slaying student council are female.
• Babies Ever After: A dark variation in the original H-Game's Downer Endings after Barmus arranges for Hikaru and her friends to become pregnant with demon children.
• Baby Factory: Barmus's Evil Plan is to force Hikaru and the rest of the student council to bear the next generation of demon children. He ultimately succeeds in the H-games's Downer Endings.
• Cute Monster Girl/Horny Devil: In the bad endings of the H-game where Barmus turns them in demons.
• Boobs of Steel: All of them are extremely busty and their main job is to slay demons.
• Demon Slaying: Their main job is to protect the school from demons.
• Dude Magnet: Each of them are among the most popular girls in their school.
• Failure Hero: In the anime, they fail to protect their school from Barmus and his minions and end up being enslaved by them.
• Faux Action Girl: Hikaru and her friends were defeated and captured relatively easily by Barmus and Kotone at the beginning of anime OVA.
• Fighter, Mage, Thief: The sword wielding Hikaru is the Fighter, Yuki is the Mage as she fights with magical talismans, while the gun wielding Seira is the Thief.
• Go-Go Enslavement
• Human Mom, Nonhuman Dad: They could end up as the "human moms", in the H-game's bad endings where they end pregnant with demon children.
• Lovely Angels: A Power Trio variation.
• Made a Slave
• Ms. Fanservice: As expected of the main female protagonists in a Hentai.
• Power Trio
• Shameful Strip: After being captured, Barmus forced Hikaru, Yuki and Seira to strip down naked to front of their peers during an assembly, before raping Hikaru.
• Trauma Conga Line: In the anime, the trio are betrayed by their mentor, are subjected to Naughty Tentacles, are coerced to make an announcement that they will basically be Sex Slaves for their schoolmates, made to perform a Shameful Strip at the school assembly, and finally Hikaru is raped by her Arch Enemy non-stop until she is driven insane while Yuki and Seira can do nothing but sob as they are Forced to Watch. Then there is the implication that they end up as Sex Slaves and Baby Factories to a bunch of demons for the rest of their lives.
• True Companions
• Wake Up, Go to School, Save the World: Well they ultimately fail on that last part.
