He is shown to be kind but he himself refers it to as his own selfishness which makes it look like kindness and hypocrisy to others.

History
Kei came to Sakurada when he was still in elementary school. That day, he took a train to Sakurada on his own. He met a member of the Bureau who handed him a phone with the Witch connected. The Witch told Kei that if he comes to Sakurada, he will never be able to leave and see his family again. Kei rejected her warning as he is curious to see the special abilities found in Sakurada.

When arrived, his keyholder broke. A member of the Bureau fixed it with his ability. Excited to see more, Kei quickly left the station to explore. Soon, Kei found out that he has awakened an ability: Memory Retention. He soon came in contact with the Bureau formally, making a contract with them. As a result, he is to stay and live in Sakurada forever. Kei was ready to face what the future brings him.

Then, Kei experienced the effects of a Reset ability for the first time, bringing him back to the station.

Misora Haruki
Kei is a classmate of Misora and has known her from middle school. They first met on the rooftop of their middle school due to Soma's arrangement and later Misora acknowledges Kei for his effort in saving someone using Misora's ability and completely trusts Kei and his decisions.

Although it does not seem so, she starts to become attached to Kei and even starts to feel jealous of him hanging around other girls, in one instance she tells Kei that he has been befriending a lot of girls.

The two became a couple after the incident of Soma's death (After reviving Soma).

Sumire Soma
She is a classmate of Kei. She put a 'love' letter in his shoe locker asking to meet on the school roof, there Kei met Misora for the first time. After talking with her Soma came to the roof, which seems her intention was to have Kei and Misora meet.
