One day as he was teaching to Yuji and the others he suddenly got teleported he got into defensive position until he noticed his body, was much shorter and he felt weird nostalgia, he looked around and saw he was at the front of his old jujitsu school “what the..” was he teleported to the past. Wait that meant- Suguru was alive! Then he saw you and his eyes watered “Suguru..?”
