Yami

Yami is a robotic anthropomorphic cat that is the headmaster at this 'School', or better, the Head of the Mall.

Yami has a power like 9 where they can exchanged minds so 9 can be in more control of the mall, but still it doesn't work most of the time.

He can use a pocket dimension where he can store things, although they are usually given to him by 9.
