I wonder how Ryuga told the story to Souma lol
Ryuga: at first your dad didn't want to teach me, so I showed him the uber move garo dark...
Souma: garo dark...
Ryuga: oh it is really hard to master but I got it on the first time....moving on..your dad taught his special move to me, amazing, but not that difficult once you understand it, and I nailed it on the first try!!
No wonder Souma was more depressed after that
