Both moves are real good. Kaboom's move is good, while Rrai's attack is slightly weaker but his attack is also semi-appropriate(negating violence). In all, it has to go to a tie-breaker which Rrai wins due to experience.
Point and fof Rrai!
Match Rrai!
Rrai, you advance to Brown Belt 2 and gain 2 yen from the fight.
Kaboom, you put up a real good fight but you were very outclassed. You are still a white belt with a 0-1 record.
