I see so many people writing about Choso being Yuuji's brother but y'all,,,hello??Like the same thing we've been talking about which is Choso suddently getting memories of Yuuji being one of his brothers happened in a different way with Todo.Todo suddently got memories of Yuuji and him being best friends,as close as brothers in Kyoto School arc and immediately stopped fighting to kill but to make him get stronger.I still strongly believe all of these happened bcus of Yuuji's cursed technique which is memory manipulation,they don't have blood connection but Choso has a very strong memory collection in his mind that allowed him to be able to share the connection he had(with his actual brothers) with Yuuji.(⊙…⊙ )
