[@ColourlessKing] it does though if he is going to be a FUG slayer I would be interesting why he wants to take that

Idk maybe so he can get close enough to Gustang to slay him and then take over? The perks are useful especially Workshop connections.

Also considering he is trying to find his own happiness away from Zahard the Families probably higher chance of joining Wol Ha Ik Song. FUG could be the darker path where distancing himself isn't enough.
