Chifuyu Matsuno/Relationships

Keisuke Baji
Chifuyu first met Baji when he was a 12 year old delinquent who had conquered the entire school, even the upperclassmen. He didn't think much of Baji, as he had just flunked last year and was held back. In addition, he was dressed like a nerd but was horrible academically. Chifuyu helped Baji with a letter he was writing, causing Baji to grin in gratitude.

Later that day, Chifuyu is ambushed by a biker gang, Mandala, because he had assaulted one of their underlings. He is surrounded and horribly outnumbered, but Baji appears and singlehandedly wipes all of them out. Chifuyu is amazed, and Baji becomes the first person he truly respects, prompting him to join Toman afterwards. Their close relationship is marked by their tradition of splitting a Peyoung Yakisoba.

After becoming Baji's right-hand man, Chifuyu continues to loyally support and place his complete trust in him. When Baji planned to join Valhalla as a ruse, Chifuyu willingly accepted to be brutally beaten up in order for Baji to be trusted by the gang's executives.

When Baji is about to die, Chifuyu holds him and is the last person he talks to. Baji reminisces about their origins by musing about splitting a Peyoung Yakisoba. Chifuyu shakily echoes the sentiment. When Baji dies, Chifuyu screams in anguish. Later, Chifuyu upholds this final request by splitting a yakisoba by Baji's grave with tears flowing down his face.

Takemichi Hanagaki
He often acts as an advisor to Takemichi, helping him create plans before taking action, giving him advice or being his emotional support. Chifuyu was the first person from the past that Takemichi revealed to him that he came from the future, making clear his great confidence in him. Takemichi and Chifuyu would eventually become best friends, with an unmatched trust between the two. Chifuyu often calls Takemichi "partner".
