Starry Sky - Season 1 Episode 7 Aries I

Kazuki's life is shown in a flashback and the discovery of his power to see the future is revealed. Due to his unawareness of his powers, Kazuki blamed himself terribly for the loss of his parents. Ostracized by others and feeling as though hiding his weakness would make him strong, Kazuki was all alone until he met Tsukiko who taught him that only cowards hide their weakness and use brute force to fight. It is revealed that Kazuki became friends with not only Tsukiko but Kanata and Suzuya as well when they were younger but when separated due to an incident with Tsukiko, those times became only memories of the past though Kazuki always promised he would remember Tsukiko even if she forgot about him.
