An ordinary boy who gets roped into the Half-Priced Food Lovers Club by Sen after witnessing one supermarket brawl for half-priced lunch boxes.
Accidental Pervert: Not that he doesn't have plenty of perverted thoughts as well - it's just that there's never any overlap between his fantasies and the numerous public situations he finds himself in.
Bash Brothers: With Ren, which earns them the nickname Two Dogs from Orthros.
Blood Knight: Satou doesn't want to get easy bento by joining up with the Hounds, he wants to fight hard for it or else it doesn't taste good.
Butt Monkey: Mostly due to Ume. He gets slapped every single episode. So far, he's been stripped butt-naked four times (One by Ume, the others were accidents), and was burned naked in the incinerator when trying to save his clothes from getting thrown in. He grows out of it by the end of the show... mostly.
Dangerously Genre Savvy: The final episode has him running around blocks so he would starve himself and make himself even more aggressive during the fight. He also delays the Club of Heracles so that the food's smell would permeate the entire store, thus getting everyone extremely hungry.
Embarrassing Nickname: The Pervert, after he had to get to a supermarket in women's clothing to get there on time. It's a Long Story, except not - an overzealous security guard made him strip and sought to Ass Shove him with a D Battery for asking to go to Shaga's room, forcing Satou to flee without his clothes.
Gag Penis: In episode 7 Ayame thinks he's using his as a rudder. It's actually the arm from the Half-Pricing God's costume.
Iron Butt Monkey: He escapes being burned in an incinerator with only a couple of bruises. And again in Episode 8, where he falls off a five-story building and lives. Those bandages were even only for show (a prank that Ayame pulled on him); he's perfectly fine.
I Want My Beloved to Be Happy: When he learned in volume 11 that Sen was in love with Yuu but Yuu rejected her, he challenged him to a bento brawl, where he had to accept Sen's love if he lost. This counts as an example because Yō himself had feelings for Sen, and he still did all that (and beat Yuu) despite said feelings. Fortunately for him, Sen chooses him in the end, having learned from Ume what he had done for her.
Male Gaze: Comes with being the viewpoint character.
Never Live It Down: invoked Doesn't matter if you didn't have a choice; go to the supermarket wearing women's clothing just once, and you'll be forever branded as a freak or pervert. There were also other "incidents" that helped make that brand stick.
Covert Pervert: Starts out as this, then ends up throwing the "covert" part out of the window. To wit:
When Satou asks her if she wants to join the Dogs, she thinks he wants to know if she wants to get gangbanged. She doesn't reject the idea outright, just says she'd prefer her first time to be one-on-one.
She's currently writing a yaoi novel involving Satou. Episode 9 says it has ten-thousand readers for the week she's on.
You: What are you doing? Hana: Nothing. Just making a text. You: Liar. Why are you pointing the lens my way? Hana: I'll only take five or so! You: Five what!? That's not the issue here! Hana: But only your crotch! You: What the hell!?
Terrified of Germs: She seems to be this for other people - she doesn't want to use chopsticks to eat a bit from a meal that someone else is going to use more thoroughly right after, and she's constantly cleaning off Satou's hands whenever he happens to touch her.
A pair of twin sisters with identical-sounding names and one nom de guerre between them, who are the respective Student Council President and Vice President of Ayame's school.The elder, long-haired one fell in love with Sen because she defeated Monarch.
Not-So-Harmless Villain: They're introduced as quirky characters who seem to know a bit about the brawls but are too silly to be credible participants. They then proceed to curb stompalmost every single named wolf in the show during the course of one fight note the exceptions being Monarch, who they've already beaten, The Wizard, who's out of the country, and who would later curb stomp them when he returned, and Matsuba, who's retired.
Cordon Bleugh Chef: She makes a bento for Satou to eat. He finds it doesn't taste bad... but the individual pieces taste like absolutely not what they have any right to (like a piece of broccoli tasting incredibly sweet) and scares the hell out of him.
Ayame carries a Protective Charm to...well, protect herself. Ayame initially warns Satou to avoid Asebi's touch, and when Satou asks why she let Asebi touch her Ayame pulls out the charm and it darkens when she puts her hand near it.
In episode 11, her playing in a garden and catching a butterfly is quickly accompanied by over 10 caterpillars going down their strands and falling to the ground dead.
Class Representative of Satou's class and Oshiroi's childhood friend who's a bit too possessive of her. Fond of abusing Satou in retaliation for any perceived slight against Oshiroi, no matter how small.
In-Universe, one of Satou's classmates thinks she's this... as long as Satou's the one getting abused.
Despite it not being true, at the end of the episode, Satou ruminates "There really... might be some appeal to this.".
Catch Phrase: "May I <insert threat>?" (One should note that she only says this right after actually beginning to act on the threat.)
Character Development: In volume 10, after she gets soundly defeated in a bento brawl while trying to protect Hana, she realises her powerlessness, and entrusts the protection of Hana during bento brawls to Satou, the guy she abuses on a regular basis. She still smacks him around, but for more legit reasons now.
Gag Boobs: Her recipe the Omelettits. However they changed the name into that without her asking her though
The Chessmaster: Despite her policy of not getting involved in the bento battles, she does a lot to actually set them up, Including inviting all of the Wolves to the same waterpark for a bento battle in a pool
A wolf from another town responsible for the downfall of Orthros three years ago. Rather than beating the twins in a fight, he reasoned that they were so strong that they were disrupting the balance of the brawls. His solution to this was to simply let them walk up and take the bento they wanted, and then begin fighting after they left.
The Coats Are Off: He does so after he realizes his plan won't work a second time. Complete with an "I'll Show You..." statement. Subverted as he was on the very wrong side of a Curb-Stomp Battle.
