Saiki Kusuo/Relationships

Saiki Kurumi
Kurumi is Kusuo's carefree mother. She played a major role in Kusuo's development and is the main reason why he doesn't use his powers for evil. She loves her family a great deal and is ecstatic to see Kusuo making friends. She does snap when people try to harm her family. Kusuo respects his mother and sees her as a kind, but too trusting person. He is a little frightened of her when she snaps.

Saiki Kuniharu
Kuniharu is Kusuo's father. He is more open to taking advantage of Kusuo's powers. He, like his wife, loves his son a great deal and is excited to see Kusuo's friend, though he sometimes enjoys seeing Kusuo in his misfortune. Kusuo pays very little respect to him ever since he was a little baby. He usually refuses to help his father, whom he thinks would become too dependent on his powers, though he can be bribed with coffee jelly.

Saiki Kusuke
Kusuke is Kusuo's competitive older brother. They have been competing with each other ever since they were little. However, Kusuo with his psi powers would always win against the genius Kusuke. Kusuo always thought that his brother hated him for always winning, but Kusuke is actually obsessed with Kusuo. He enjoys competing with his little brother even though he knows he will lose. In the future where Kusuo dies early, Kusuke is happy to see him since life was boring without him. Kusuo does not like his brother very much. He finds his brother annoying and wants very little to do with him.

Yumehara Chiyo
Chiyo is one of Kusuo's classmate who fell in love with Kusuo. She fantasized about him and tried to get closer to him. However, Kusuo easily foils her plan and she was able to move on. After three months, Chiyo once again started to think of Kusuo as her relationship with her boyfriend was souring. Kusuo tried to get them back together but failed in the end. Kusuo eventually was able to get her to fall in love with Kaido.

Teruhashi Kokomi
Kokomi noticed Kusuo walking alone in town. She tries to "improve" his summer by chatting with him, but Kusuo barely acknowledged her. She assumed he saw her as an illusion and that he was too infatuated to see her. She tried to get a reaction out of him, but failed after Kusuo teleported away. Kokomi ended up thinking that he was an illusion and she was the one in love with him. Kokomi is persistent on getting Kusuo to acknowledge her that she'd go that far as to eat some gross ramen with him and his friends, something that impressed him. After Kusuo erases her memories of his mother's comment of his psi powers, she ends up thinking that Kusuo had a bad experience with a girl he liked. On Valentine's Day, Kokomi brought chocolates for Kusuo, but wasn't able to give it him because she’s afraid he’ll get beaten up if she gives it to him so she throws it away. Kusuo catches it anyway. During the school trip, Kusuo saves her from a bear. She assumes it was a dream and makes "Kusuo" acknowledge her. Kusuo sees Kokomi as a nuisance as she attracts too much attention. He tries very hard to make her hate him, but every attempt was unsuccessful.

Nendou Riki
Riki is a classmate who's mind Kusuo cannot read due to him being an idiot. Riki often asks Kusuo to eat ramen and calls him partner much to Kusuo's dismay (even Nendou's father call him partner).

Kaidou Shun
Shun is a classmate and chuunibyou who went on to great lengths just to befriend Kusuo. He went around Kusuo's neighborhood just to find the alien in his drawing which was actually Kusuo. In the end, Kusuo had no other choice but to show up with the face of the person in his drawing. Shun then started following him around, much to his annoyance.

Hairo Kineshi
Hairo is the class representative of Kusuo's class. He is a hot-blooded boy who is reliable and gets along well with everyone even towards the outcasts like Kusuo and his circle of friends.

Rifuta Imu
Imu is a junior classmate who was used by Kusuo in order to make Kokomi leave him by making it look like they were dating. However, when he tried to go along with it, it backfired and Imu started liking him for real. She later realized that it was Kokomi that she likes.

Aiura Mikoto
Mikoto is a Sooth Sayer and one of the few who knows about Kusuo's powers. After witnessing his powers, she started stalking him and tried to get close to him. She is a member of Occult Club with Kusuo, Chiyo, Reita and Arisu.

Toritsuka Reita
Reita is a Spirit Medium and one of the few who knows about Kusuo's powers. He found out from a spirit who saw him use his ability. Reita is the reason why Kusuo developed the power to see ghosts. Kusuo ranks Reita as his number one most hated guy and usually messes with him like when they were dividing pairs for the test of courage and Reita wanted to be paired up with a Arisu but he paired Reita with Chiyo.
