Protag learns that his former student with the Clown job decided to become a notorious thief for funsies (this is actually revealed before c65 but is relevant for the below point.)

Said thief starts freeing "calamity" anthropomorphized weapons for funsies, dropping unresolved plot threads about one weapon who was the only male weapon produced who killed their master and is still at large.

Protag becomes a professor as part of mandatory process of becoming A rank (no new students of notes were produced as a result of this.)

Protag learns his lifespan has shortened due to pursuing Holy at all costs in his youth.

Protag creates a rejuvenation potion that only works on himself because of a niche skill he got a long time ago which had no use until now (the above point and this one happen within the span of like 5-10 chapters.)

Protag gets dragged into a love triangle between the elf woman headmaster and an as*hole elf misogynist professor.

Clown thief trolls everyone at the academy into self-destructing (socially) after just sending a calling card to the academy, causing the misogynist professor to (unsuccessfully) frame the protag and the headmaster to drag the protag off to the elf country to help train young elves and prevent magic circles from becoming lost art.

The nagging god who's been visiting to protagonist in his dreams cryptically reveals that an assassin the protag trained (and who has been a messenger involved in the plot recently) is actually the spawn of a different god than the one talking to protagonist and may come into conflict with protag in the future.

A "rocks fall, everyone dies" death is inflicted on a bus of 35 individuals back on Earth, explicitly as a tie-in to the author's new story.
