you where talking to chuuya and dazai as you were walking down a path when you see someone with a red shirt blue pants and a straw hat on running up to you, you know exactly who it is as he comes up to you

Luffy: hey! Hey! I haven't seen you in so long

Luffy says in his cheerful tone

Dazai: uhm who are you

Chuuya: yea who are you

The two seem very confused as you stand there looking at Luffy
