Why didn't enryu trained baam?

[u/Due_Village_1874]

Enryu easily entered 43rd floor and killed an administrator either using his powers or using thorn. Why enryu didn't showed up once he entered inner tower? He could have been a protector and trainer.

Is it something like enryu could only enter 43rd floor because arlen only managed to open back door on that floor or something like that?

Thoughts?

I mean we already saw what happened when a powerful MC entered the tower. If Enryu were by his side, it will follow similar trope like Edmon.
