Chika Kudo

Prior to the start of the series, Chika was neglected by his father and was caused to live with his grandfather, Gen Kudo, instead. During these days, Chika would always get into fights and is infamous because of this. Despite this, Tetsuki Takaoka was close to him and would often come to Gen's house to check up on Chika. Through his grandfather's attempts, and also Tetsuki's reaching outs, Kudo starts to become mellow. Unfortunately, the bad crowd he was hanging out with disliked this and set Chika up by ransacking his grandfather's house where he crafts kotos that he is blamed for this by the neighbors and the police. Not long after this incident, Gen passed away due to a heart disease and it is revealed that Chika now lives with his paternal aunt, Isaki Kudo, after Gen's passing
