Kelego was already my absolute favorite from Iruma-kun but my god he's now even higher. One of my favorite manga characters of all time now, I just can't explain how much his character has made his way into my heart, just love his archetype of a character so much.
A teacher who literally would resign to protect a student, even when that student is effectively no longer one, while also making sure the rest of his class will be fine with teachers he trusts and feels can grow with the kids.
Like how can you not love him?
