Beware of Unmarked Spoilers.
Tori "Impossible" Aoi
Protagonist of the series, Tori Aoi's a carefree young man of utterly average talents. He was placed as President of the Musashi Ariadust Academy Student Council because he thought it'd be easy to control, and even recognizes himself as a poor leader. He doesn't seem to care much, and enjoys his role at his own leisure. He knows a lot of strip jokes and usually plays the idiot. Tori is also the energy of Class 3-Plum, literally: he acts like a living mana battery that can recharge and supply his companions with unlimited reserves, controlling a quarter of Musashi's ether supply, thanks to being one of two viceroys in the city.
- All-Loving Hero: Despite the goofy pervert he might be, Tori is an optimistic and selfless guy who wants to create a world where everyone's dreams would come true, a belief that earned him the respect of everyone in Musashi.
- All Work vs. All Play: All Play to Masazumi's All Work.
- Attractive Bent-Gender: He looks pretty good in a dress and has fun fooling men with this.
- Butt-Monkey: If there's someone here that will always end up getting beaten up, that's Tori. However, he's kinda asking for it with his perversions.
- Buxom Is Better: He certainly thinks so; in fact, when he writes down a love letter confession to P-01s/Horizon, his classmates are surprised he doesn't mention her bust size in describing the automaton's "positive traits".
- Childhood Friend Romance: He is in love with his childhood friend Horizon. Later in the light novels, he gets a small harem formed by Horizon and his other childhood friends Asama and Nate.
- Childhood Friends: He has been friends with several of the members of Class 3-Plum since childhood; Asama, Nate, Suzu and Tenzou among them.
- Chivalrous Pervert: He's a huge pervert who loves groping girls, but he genuinely cares about his female companions, especially Horizon and he only wants to create a better world for everyone and bring back the emotions of the woman he loves.
- Conveniently Seated: He sits in the back seat next to the window.
- Dark and Troubled Past: He saw his childhood crush getting run over by a carriage and dying right in front of him. To make it worse, the reason she got in the way of the carriage was because she was trying to get away from him after he insulted her cooking.
- Embarrassing Nickname: He doesn't like to be called "Wet Man".
- Fluffy Fashion Feathers: Has feathers adorning the shoulders of his uniform.
- The Heart: He is the one who encourages his crew whenever they feel down and gives them the will to keep figthing no matter what.
- Heart Is an Awesome Power: His support powers don't mean much to his friends when they reside in the city and academy grounds of Musashi, as these places are rife with ether for their daily needs and training. Outside Musashi, however, Tori is the key to success, as he can supply his allies with infinite ether reserves to continue fighting without worry.
- Heroic BSoD:
- Watching P-01s/Horizon get taken and being unable to do anything about it.
- He suffered a severe one when he was a child after losing Horizon. He refused to eat or drink and only stayed in his room throughout the day until his sister Kimi snapped him out of it.
- Hidden Depths: At first glance, Tori is just an idiotic pervert that no one could take seriously as Musashi's chancellor, but he's actually quite smart when the situation calls for it, serves as Musashi's energy source both figuratively and literally, and he has some deep emotional issues coming from losing the girl he loved and blaming himself for it.
- I Let Gwen Stacy Die: For many years, he felt responsible for Horizon's death, for the carriage accident wouldn't have happened if he haven't chased after her.
- Keet: He's loud, optimistic and full of energy. He literally does not know the meaning of "depressed". With good reason, too.
- Large Ham: He sure enjoys acting in a ridiculous over-the-top manner.

- Living Battery: When Toori gains the 1/4th governance status in Musashi as a Viceroy, he is given the authority to use 1/4th of the fuel of Divine State of Musashi. Since his contract allows him to share everything he owns with everyone, he can provide an almost endless energy supply for his comrades, improving their abilities to the fullest.
- Lovable Sex Maniac: A complete pervert who shamelessly gropes and sexually harasses girls, even his own teacher and loves to read porn magazines and play eroge games. Yet his perversions are always Played for Laughs and he only gets a few smacks as punishment.
- The McCoy: Always cheerful and optimistic, Tori is driven by his emotions and instincts.

- Naked People Are Funny: In Season 2 except for a few scenes.
- Non-Action Guy: Not the useless kind, but he's plenty lacking in the combat field.
- Obfuscating Stupidity:
- When debating against Masazumi Honda on rescuing Horizon Ariadust from the K.P.A. Italia, he took the stance of not rescuing Horizon, thereby forcing the more adept-at-debating Masazumi to take the opposite stance. Not pleasant, but actual debating does assign people to motions they should defend regardless of personal preference.
- In episode 12, Horizon consigns herself to death; Tori argues against her views by using a parallel argument and convinces her to leave with him.
- Opposites Attract: He is a loud, goofy and fun-loving Keet while the woman he loves P-01s/Horizon is a quiet, analytical and no-nonsense Emotionless Girl.
- Perpetual Smiler: He rarely stops smiling, no matter what happens. Justified since if he ever stops being happy, he literally will die.
- Personality Powers: He sure is energetic, isn't he? Perhaps he got some to share.
- The Pollyanna: There is nothing that can depress this guy. He will always see the bright side of things no matter what. Justified since as a condition to his contract to the Asama Shrine for his powers, being sad will literally kill him.
- Red Oni, Blue Oni:
- The loud, happy-go-lucky and emotional Red Oni to Horizon's quiet, emotionless and analytical Blue Oni.
- Also the carefree and outgoing Red Oni to Masazumi's more serious and reserved Blue Oni.
- Robosexual: He is in love with the automated doll P-01s. Although he fell in love with her back when she was a human.
- Scars Are Forever: Has a scar circling his left shoulder.
- Shameless Fanservice Guy: He has no problem with stripping naked in front of his entire class or going around naked for most of the second season.
- Smarter Than You Look: Despite all that goofiness and perversion, Tori is quite sharp.
- Spanner in the Works: If his move under Obfuscating Stupidity doesn't earn him this title, pantsing Masazumi and throwing off Pope President Innocentius' attempts to undermine her definitely does.
- Student Council President: He is the president of the Musashi Ariadust Academy Student Council, which in this series equals to the position of a chancellor.
- Thanks for the Mammary: Often, specifically with Makiko Oriotorai, Nate Mitotsudaira, Suzu Mukai and Horizon.
- Unable to Cry: His contract has as a condition that he can never cry or feel sad, otherwise he will die.
- Unwitting Instigator of Doom: The day Horizon died, she cooked breakfast for him, but he said it tasted terrible. Horizon ran away crying and Tori chased after her. As Horizon tried to get away from him, she got run over by a carriage which resulted in her death.
- Useless Protagonist: Subverted. As his nickname "Impossible" suggests, there seems to be nothing Tori can do and his companions have to handle everything instead. However, Tori proves himself useful when he resupplies his companions' energy. Also, his Obfuscating Stupidity helps in some situations.
- White Mage: A rare male protagonist example, as he buffs and resupplies his allies' energy.

The heroes make their goal to gather the nine Armors of Deadly Sins to bring Horizon her emotions back and stop the apocalypse.
- Mystical White Hair: She's an automaton who has silver hair, which hints at her artificial origins and the fact that she is an Armor of Deadly Sins and has a human soul.

- Uptown Girl: Horizon is a member of the privileged Matsudaira family, while Tori comes from a family of loyal servants to her family.

She eventually does come to develop feelings for him and this makes her wish to understand human emotions more.
Student council vice-president, Masazumi is serious-minded, skilled in speaking, and hard-working; effectively, she's Tori's exact opposite.

- A-Cup Angst: With a damn good Tear Jerker reason, too. She had to undergo a mastectomy in preparation for her gender reassignment when she was younger. She's understandably sensitive about her flat chest.
- All Work vs. All Play: All Work to Tori's All Play.

She also chooses male clothing because it doesn't feel right to her to dress like a girl after trying to change her body.
- Big "WHAT?!": After Tori chose the side of not rescuing Horizon during their debate.
- Dark and Troubled Past: When she was young, Masazumi wanted to officially inherit the name of Masanobu Honda's son after her father failed to inherit Masanobu's name.

However, Masazumi lost her reason for the name succession after Motonobu Matsudaira replaced his vassals with automatons. Years later, her mother suddenly disappeared and was later reported as spirited away. After this, she moved to Musashi with her father.
- Foil: To Tori. He is well liked by his classmates yet not taken seriously by most people, and he constantly slacks off and is no good as a leader.

- Gender-Blender Name: Masazumi is a masculine Japanese name.

- Wholesome Crossdresser: She initially wears a male uniform because she finds it uncomfortable to wear girl's clothes after trying to reassign her gender.

Kimi: Listen. This is what you just said, "If I die, it's because of you, Knight. I got beaten to death, but I did it for you and don't you ever forget it." You think sacrificing yourself is enough to stay with someone?
