okay so thanks to kris i remember that the other pairing i want to xover with 1827 is kaichi

and you know

kage x hina : 1st grade high school

abemiha : 1st grade high school (i think they should have advanced to 2nd by how long it’s been now?)

gareki x nai : nai is questionable but gareki should have been in high school

kai x aichi : kai is on 3rd(?) grade high school and aichi around 1st or 2nd(?) high school

HIBATSUNA IS STILL THE YOUNGEST

OMG
