The 4th Great Ninja war has started few time after Naruto starts his training. Edo Tensei is making a lot of problems and the lot of white Zetsus too. It's the middle of the night and you received the warning that the white Zetsus are killing in secret.

You were taking some air while others were making some patrol in turns. You saw a shadow. You for no reason followed it. You saw Deidara.

Deidara: "How can he stay alive...? That was my Ultimate art! I need to make a better art! Uhmm!"
