Just want to clarify, the yellow samurai sword. Is like a character, it is built to stun everyone and everything.

This is Knightball. Loves technology, books, and tea. But it also likes to run around laughing maniacally and bombs everything around it.

If he disapproves something, it stuns the problem with its sword. It does not use the sword to kill, just stun.

Oh, and he is extremely pacifist.
