Yep, pretty much! Besides weapons there are ones that turn into clothes, or things like earrings and fans, or even animals.

It's not really up to you though. You just are what you are. Don't worry though- no matter what you turn into, your god is responsible for finding the best way to use you.

[If he hears of any god neglecting their shinki and not calling them-- Well, he'll try to not get angry over that until it happens. If it happens.]
