Takemichi Hanagaki is a 26-year-old man whose ordinary, disappointing life is shattered after he learns that his middle school ex-girlfriend, Hinata Tachibana, and her younger brother, Naoto, have been killed in a conflict involving the infamous Tokyo Manji Gang (Toman). After a mysterious accident, Takemichi is sent exactly twelve years into the past, back to his middle school days, where he discovers he can travel between the past and present by shaking hands with Naoto. Determined to save Hinata and change the future, Takemichi throws himself back into the dangerous world of delinquent gangs despite having no exceptional fighting skills, relying instead on his unwavering courage, determination, and refusal to give up. Along the way, he befriends Toman’s charismatic and kind-hearted leader, Manjiro “Mikey” Sano, whose carefree personality hides immense strength and influence, as well as Mikey’s calm, intelligent, and fiercely loyal vice-captain, Ken “Draken” Ryuguji. As Takemichi becomes entangled with Toman, he witnesses the loyalty, brotherhood, rivalries, and brutal gang conflicts that shape the future, including violent clashes against gangs such as Moebius and Valhalla. Every decision he makes in the past creates ripple effects that alter the future, forcing him to repeatedly return through time in an attempt to prevent tragedies, protect his friends, and stop Toman from becoming the ruthless criminal organization it is destined to become. Season 1 follows Takemichi’s emotional journey as he struggles against impossible odds, forms unbreakable bonds, uncovers betrayals, faces heartbreaking sacrifices, and learns that changing fate requires far more than strength—it demands unwavering resolve, selflessness, and the courage to stand back up no matter how many times he is knocked down.
