Now featuring the very quickly machine translated hints

A masked playwright directs the wonderful opening!
With the security chief Tengu, has the time finally come to surpass his master?
A reclusive animal chemistry student follows his idol and tries his hand at a part-time job!
The nurse at the emergency room recalls the season that should have passed in the shadow of the problem child?


I'm too sleep deprived but

Oscar's obvious

I can't say for certain for the second one I'm assuming security chief Tengu refers to Raven Arthur and I can only Ulaanbaatar and Akiha Gongen since they are fire fighters. But Akiha already has a Summer Alt.

Yuma is the third one I think?

As for the fourth character please tell me I'm wrong. But even if it says the emergency room nurse and with problem child in the same sentence. I can only think of is Shennong. If so how? He already has a Summer alt and I'm having such mixed emotions right now.
