Yes this is a crossover with kuroko no basket fight me

one time hinata and kageyama ran into kuroko and kagami at a sports festival type thing

they surprisingly got along somewhat well

 ( kageyama and kagami were silently fighting each other )

but hinata and kagami ended up having a jumping contest to see who could get the highest

tho there was a storm and everyone had to go home

to this day there still isn't a winner
