LoRA of Sensei from Blue Archive. Includes his 3 main versions: the anime, the manga, and the arona doodle mask. Outfits may have small inaccuracies.
Triggers:
Anime Sensei: senseianime, black hair, collared shirt, necktie, id card, grey suit
Problem Solver Sensei: senseiproblemsolver, glasses, coat, id card, black hair, black shirt
Doodle Mask Sensei: senseidoodlemask, mask
I suggest adding some hair tag to the doodle mask.
