 It could be speculated that deep down, Onizuka knows when he's acting immature, and allows others to keep him in line.An example of this is when he forces his students to dig for buried treasure during the Okinawa trip.Urumi Kanzaki kicks Onizuka into a hole, and later forces him to wear S&M garb and has him crawl around on all fours, with Urumi riding on his back.
