Ryusei Satou

Ryusei Satou is the former Tokyo Manji Gang First Division Vice-Captain (壱番隊 副隊長) and the leader of Yotsuya Kaidan. He is the deuteragonist of the Tokyo Revengers: Letter from Keisuke Baji spin-off series.

Appearance
Ryusei has tan skin and has dyed, messy pink hair with a few black strands. On his right ear he sports a ring earring with a tassel. He has droopy dark eyes with long eyelashes on the bottom and a snake tattoo on the left side of his neck. Ryusei is usually seen wearing a faux fur coat over a black t-shirt, and occasionally the standard school uniform. He is considered handsome by his female classmates and himself.

When he was younger, Ryusei had black hair and was styled close to a bowl cut.

Personality
Ryusei has a very laid-back attitude. He is very calm, even in the face of very difficult situations. He is quite confident of himself, always calling himself handsome and that along with his friendly personality makes him very popular among his peers. He is very playful and likes to tease. He is also very cunning which makes it easy for him to mess around with people, he often messes with people for fun. For example, he offered Chifuyu help to get recognition from Baji by giving him a new hairstyle, but he styled Chifuyu's hair in a hilariously overdramatic and large pompadour. Chiufyu finds Ryusei's playful personality very annoying. Despite Ryusei's knack for messing with people, he seems to actually be a very caring guy as he was one of the few people who visited a wounded First Division member, Cho, every day, leaving him flowers and gifts. He saved Chifuyu from getting beaten by an opposing gang member even though Chifuyu openly showed his dislike towards him. He also greatly respects Baji and provides him with utmost protection when necessary. His truly kind personality was even recognized by Peke J, Chifuyu's cat. He doesn't mind being viewed as a narcissist if it means he can help his gang.

Underneath his relaxed and spirited personality seems to lie much turmoil. He seems to have a very violent side as seen when he almost killed the leader of the gang Killer Bee which may have something to do with his past relationship with Yotsuya Kaidan.

Authority
He is the first division vice captain of Toman. He has control and command over the division. Also as the leader of Yotsuya Kaiden, he has command over the entire gang.

Fighting Prowess
He is an extremely strong fighter who can take down entire gangs all by himself like Yagyō Dōji. He seems to be an expert on boxing and knows various useful and important fighting techniques which gives him a great advantage compared to others. He can also easily distract his opponents which makes it even easier for him to defeat them. He was able to defeat Killer Bee, a very big and powerful gang with only one person, Matsuno Chifuyu, by his side, all the while protecting Baji.

His strength is such that he has the respect of Baji who openly acknowledges his strength.

Intelligence and Charm
He is a very intelligent individual who can read and understand people, including his opponents very well. He also seems to know a lot about boxing and fighting techniques. He is incredibly charming which makes it easy for him to deceive people, he has everyone at his school thinking he is a sweet, harmless, ordinary guy when he truly is a dangerous delinquent. He is very cunning which helps him not only mess around with others but also trick and distract his opponents which makes it even easier for him to defeat them. These traits are what is most fearsome about him and what gives him an edge over others.
