Anton Crociws, the Head Librarian (Patreon)

The crow magician.
He became a half-creature due to a influence of magics.
His motto is "Knowing is the life, pursuing is the nature.".
Following his motto, his hobby is collecting books, and he opened the library filled with his collected books.

Of course, due to various weirdos bugging him and having a meeting in the library, he's really uncomfortable about it.
Still, he just lets them slide since they learn various knowledges.
For him, it's interesting to watch what they're trying to do.  

He's a coffee addict,
and living an attic inside his library which has a bird's nest.
He's really older than his look since he became a creature,
which made him not getting older.
