Curious, she travels into the past through her family's secret time-doors and found out that he is actually her childhood friend, Kairi! She's upset when she came back to the present and saw Shinjo turning to Kairi. He has no recollections of being 'Shinjo', but he still remembers his childhood days with Aira. What will Aira do?
