how does choso find out that yuji is his brother

Choso finds out Yuji is his brother when a flood of false but emotionally convincing memories hits him during their fight in the Shibuya Incident, making him “remember” Yuji as one of his siblings. Later, the story confirms the relationship is real in a twisted way: they’re half-brothers through Kenjaku, who is connected to both of their births.

What happens

• In the battle, Choso is about to finish Yuji off.
• Suddenly, he sees a memory of Yuji sharing a family moment with him and his other brothers.
• That memory did not actually happen, but it changes Choso’s entire perception of Yuji.

Why it matters

• Choso has a special ability tied to sensing his brothers, so the memory-like vision hits him hard.
• After that moment, he starts treating Yuji as his little brother and even switches sides emotionally.

The real connection

• The relationship is not based on ordinary family history.
• Yuji and Choso are connected through Kenjaku, which makes them half-brothers in the story’s lore.

Tiny spoiler-free version

He doesn’t learn it through a normal reveal scene; he feels it during battle first, and the later lore confirms there really is a family connection.
