1. Every time he bets on a team, they miraculously always win. Even if he gets on an objectively bad team, somehow the renowned better doing opposers keep losing. Somehow
2. Will occasionally go on rants to anyone and also no one about how this wholly American sport should have been invented by Japanese people (I also hc that he is pretty nationalistic) in his day
3. Absolutely %100 a keyboard warrior who is occasionally active on Twitter (not really a surprise) to argue with people about why baseball is better than most (no- contact) sports.
4. He does like Hockey (the sheer brutality and also punching people parts) and Football (no explanation needed)
5. Loves going on autistic rants about why planes are so cool and awesome and amazing and also has many (many) ideas and blueprints to make them more accommodating for people of larger sizes (this is for his Heian Era form)
6. He, in deed, really likes fighter jets and has watched many playthroughs of games centered around flying and just tearing shit up
6.5 (coughs in he absolutely has watched too many CoD streams and may have acquired a new barrage of vocabulary)
7. Headcanon that he liked ⚾ enough to go to a few (at least 25) games and engage in The Usual Riffraff™:
7a. Go headfirst in autistic debates about the sport with other fanatics.
7b. Gets way too much themed things but also a few VERY rare and signed pieces from some legends themselves. Somehow he acquired a ball signed by (Insert Famous ⚾Player Here).
8. He sits in the airport too much just looking at planes taking off, landing and getting fuel.
9. He'd probably actually do some grunt work and do surprise surveys about planes on passengers.
10. Most likely almost got lost when he got enraptured by one of his favorite models (___) and strayed too close to it entrance.
10.5 he should've gotten on that plane, it was going to The Bahamas.
11. Sukuna is to ✈️ and ⚾ like Gojo is too annoying people. Can't help it; won't stop it.
12. Modern Sorcerer! Sukuna absolutely barges into Geto one day while the latter is flying on his pelican (don't ask why Sukuna was in the air) and Sukuna went on a tangent about how Helicopters and their pelican siblings need to be planes instead.
