Ok hear me out
Kurona is the type of guy to collect Lego sharks
If he ever went to IKEA or knew someone was gonna go he would get a Blahaj every. single. time.
I also think Kiyora collects soda tabs
Hiori probably collects figurines, maybe not necessarily just anime figurines but just figurines from his game in general
Also Nagi probably maxed out at least a few accounts in some of the games he plays (he has no life)
Ego might play the official Blue Lock: Project World Champion game to see just how strong everyone can get (that game has very high rankings you can get - unrealistic)
