Problem is that people can wear mask at university while classes, but no one won't wear it in campus, dormitory. It's absurd to wear mask in room where you live even if you live with 2 people. wearing mask in shower cabin is stupid too.
Even if char in teaser of TK7 SP is Kunimitsu. Don't forget Harada asked Shimbori for unknown reason. Lol Considering that every Tekken SP had a guest char. We had a chance lol
If there is doa character planned for SP4, high chance that Shinbori KNOWS who is in the teaser, because if they are working together for that collab, both sides know the details
