Habitually says "Good grief" (Yare yare).
The real reason Kusuo avoids Kusuke is because of Kusuke's perverted nature (he feels pleasure rather than frustration when losing a match). However, looking closely at his actions, his obsession with his brother isn't just due to masochism. He has a brother complex, so despite the excuse of testing psychic powers, he often looks after his brother by giving him coffee jelly, high-end snacks, or sending tens of thousands of yen as New Year's money.

The Disastrous Life of Saiki K.
Family
On a peaceful Saturday morning, Saiki is already awake and eating coffee jelly in the living room. It seems this is the only time his expression softens into something gentle. It feels as if he has finally attained "freedom"... but damn it, Kusuke is there. Kusuke is sitting in the chair next to Saiki, eating cup ramen.
