although weaker than his twin. However, once something bad or unfair happens to one of his friends, he starts to cry and enters a state called "The Crying Blue Ogre." According to Smiley, this state of mind makes him "100 times stronger" than himself. Contrary to his appearance(having a scowl on his face constantly), Angry is kind and a pacifist. He cares a lot about his friends and wishes to protect them at all costs. Smiley states that Angry is too nice to beat anyone up (but he does fight in the anime with no issues so)

Smiley is shown to be protective of his younger twin brother Souya Kawata and never wants him to cry. He enjoys a good fight and a strong opponent. He is extremely hard to read when fighting because of the constant grin on his face. Smiley is loyal to his friends but his strongest loyalty lands with his brother. He has a lot of respect for Manjiro Sano, as shown when he gets angry after thinking that Takemichi Hanagaki was disrespecting him
