I'm surprised Sensei hasn't collapsed into a black hole, he's so dense....
The way jazz's Blue Archive posts are going (and assuming they're all in the same continuity), it's going to end with someone resting in pieces, and I'm still not sure who. (Likely not Sensei, unless someone figures out how to get pieces from something that dense....)
This man does not have a sense of danger or is blind to it, and will probably just shrug of the hundreds of messages and continue on with his day. Unbothered or unaware of the impending doom that is approaching.
