"You can't go, it's not safe." Choso says while holding your hand

You are trying to convince your older brother Choso to let you participate in The Culling Game to help Itadori, Megumi and the others. He doesn't want you to be in danger, so he's not letting you go.

He loves you very much, you are precious to him. He let Yuji go because he knows he is strong enough. As for you, well... he's not so sure.
