Satou Yoh

Yō Satō is a high school freshman who finds himself dragged into the battle for half-priced bento. He enjoys playing retro video games, particularly Sega games. He is given the title Pervert (変態, Hentai).

Appearance
Satō is a high school freshman of average build. He has black hair and light brown eyes. He always wears his school uniform, even in bento brawls. He is usually seen with some bandages on his face due to getting injured in bento brawls or getting slapped by Ume Shiraume.

Clothes wise, Sato doesn't exactly have any particular taste for fashion. However, he tends to wear a white top under another top for casual get-up.

Personality
Satō has a mixed personality. He can be clumsy at times, but while fighting for bento as a Wolf, he shows his strong side and can take on much stronger opponents. He has feelings for Sen and is on very friendly terms with his cousin, Ayame. He is said to have a personality similar to that of a wolf.

Fitting to his title, he is, in fact, a pervert; he keeps around several porn magazines given to him by a classmate in his room, and Ayame hints that he started reading them at a young age, and had a variety of fetishes. He also tends to have fantasies of girls (usually Sen) and blushes wildly when they are close to coming true. Despite this, several female characters grow attached to him, mainly Sen, who is completely oblivious to this side of him and even his title; Ayame, with whom their relationship appears to have grown stronger since their last encounter; even the elder Sawagi twin; although they had an awkward first encounter, the elder twin eventually grows to like him, having apologized for what she may or may not have said to him and cheered up when he appeared before she and her sister would give in to the  Club of Heracles' s plan. More comical relationships with Yō include Hana, Ume and Asebi Inoue; all three have continuously affected Yō, with writing erotic comics involving him, constant physical abuse, and giving him bad luck respectively.

Abilities
Satō is a wolf and a member of Half-Priced Food Lovers Club. He has good fighting ability and was able to hold his own against The Storm with the help of The Wizard, and against Nikaidō, when the latter tried to test his ability. He has defeated Ayame several times, who is said to be one of the stronger wolves, and either took part in defeating other notable wolves or single-handedly defeated them, showing his remarkable skill and how it has improved since his very first bento brawl.

Sato is a very fast learner. Upon his first bento brawl and second bento brawls, he could do nothing but fall before his enemies. However, he began to improve over time. His fighting skill increased dramatically in a short amount of time, reaching the point where he could begin to defeat wolves on his own. He is also capable of faring well against storms and boars, and can fight on an okay level against Orthros.

He also has an unusual healing rate; his injuries heal rather quickly, and even actions as severe as falling off several stories only put him out of commission for a single day.

Yarizui Sen
Prior to ever meeting personally, Sen and Sato attended the same school. They never made contact until Sato decided to visit the same super market she was in one day. Upon meeting, Yarizui had easily knocked out Sato without much effort. No bad blood arose between them though, instead becoming a relationship between mentor and student. This relationship eventually progressed to one where the two could stand on nearly equal terms, even though Sato still has a long way to go before being able to defeat Sen.

Sato has a minor crush on Sen, even from his first meeting. Due to his overly strange behaviour, he had even fantasized about her before they had properly met. And even after becoming a dog and later a Wolf with his own Noms de Guerre, he has continued to fantasize every now and then. The two have a very friendly relationship, even getting angry or upset when witnessing another person defeat the other. Sato also holds great respect and admiration for Sen as a Wolf, believing her to be unbeatable. This paved the way for his shock at her defeat at the hands of Orthros.

Sen sees Sato as a proud Wolf, and a very good friend. The two have never been on bad terms with each other, not even once. She sees fit to scold or praise him as she sees fit, and her view of equality allows her to be calm even when Sato wore a his infamous skirt, cap and sailor uniform. It is also implied that she has underlying feelings for Sato, sharing her food with him and assisting him when he was in trouble.
