Keika and Ki learn more and more about Shouken's past. Shouken has special feelings for Ki, but when he tries to explain his feelings to his brother, Sekijin, he is scolded and forced to make the ultimate choice. When Ki and Keika finally reach his memories of the day when he pointed the gun at his own head, they learn the real reason that Shouken decided to take his own life.
Perhaps it was this moment when we

Talvez fosse esse o momento em
que eu não podia mais voltar atrás.
