seems like the credits are in order for this opening. Soty and Fumiaki line up. I guess I won't tag unless we get another confirmation to be sure but it should go:

1st cut: Kohei Tokuoka
2nd cut: Soty
3rd cut: NC? (could be Sannomiya but it doesn't look much like him)
4th cut: Shouta Sannomiya (alternatively fumie imai if sannomiya did the 3rd cut)
