Kai Shimada is a professional shogi player of rank 8-dan. 
~!When Kiriyama first encountered him, he noticed that Shimada had no notable strengths or weaknesses in shogi.!~

Shimada possesses a calm and collected personality. At first, it seems like he's very plain, but as seen on his game with Rei he has a very intimidating yet serene personality. 
He's observed to be caring over fellows under him like Nikaidou. Shimada is very kind to his fellow shogi players and tries to help them improve their game. 
~!He runs a study group consisting of himself, Kiriyama, Nikaidou, and Shigeta.!~

Rei Kiriyama is a 17 year old boy who recently started living alone, financed by his salary as a professional Shogi player. Despite his independence, however, he's yet to mature emotionally, and his problems continue to haunt him in his daily life. His relationship with his adoptive family is strained, and he has difficulties interacting with his fellow high school students. 
 
Meanwhile, his professional career in Shogi has entered a slump. Burdened with the heavy expectations placed upon him, his wins and losses are fluctuating as his record and progression into the ranks begin to stagnate. 
 
Acquainted with Rei are the three Kawamoto sisters: Akari, Hinata, and Momo. Unlike Rei, they live happily in their modest home, which they warmly welcome Rei into as if he were one of their own. He frequently visits the family, interacting with them and receiving the kind of care and affection he never quite had while under his foster home. 
This is the story of Rei's triumphs and failures, relationships new and old, and his growth as a person.

Through these ties, he realizes that everyone is burdened by their own emotional hardships and begins learning how to rely on others while supporting them in return.
