Unknown Weapon

"What weapon should I create? I don't know anything in this world so I just put everything in this weapon that I'll be making'

Yuu created a Unknown Weapon that forms into a tree branch, but it turn to anything what is likes to be.

"Wow, so this is a my weapon a tree branch, this is so cool hey Satan can you see this my first weapon Hahah" Satan having a freaky bad vibes in Heaven.

When Yuu finished his first weapon, he swing it accidentally and the whole universe turns into void, after what Yuu did he was so happy that his weapon is strong and didn't even know what he just did.
