A.N. — The hardest-working UA faculty member (IMO) has his birthday today. Sure, UA has a big budget, but it's because of Cementoss that they can be so cavalier about all the cityscapes they decimate. Happy birthday, Ken Ishiyama!

81. Ken Ishiyama/Cementoss

Cementoss had the highest job security of any UA teacher. Fellow faculty members Recovery Girl and Lunch Rush had their niches, but so did he. And while Ken's instruction in Modern Literature wasn't in question, he truly earned his keep through his quirk.

UA regularly destroyed facilities through training (and mishaps), so Ken was never short of work... but he wouldn't say no to extra helpers or more breaks. Cementoss might have had the capabilities of a one-man construction crew, but even his stamina flagged in the face of the sheer volume of tasks the school tossed his way.
