Kokoro Connect

Synopsis

As Taichi is forced to tell the others what he had been hiding, the second Heartseed reminds them of the consequences, making the age reverts random and including Taichi amongst those who can turn younger. As the gang are forced to stay at the building to avoid others discovering themselves, Iori becomes stressed when she believes her mother to be in danger from her violent second husband, who wants to get back together with her. After briefly turning younger for a short period and regaining memories of that age, Iori tries to head off on her own but the others stop her, asking her to let them help. As Taichi, Iori and Himeko reach the house and hear violent noises, they are forced to retreat after Iori turns into a baby. Just then, the first Heartseed approaches them, ending the age revert phenomenon and offering Iori the opportunity to go back in time and rectify some of the bad decisions she made in her youth. After some encouragement by Taichi and Himeko, Iori declines his offer, saying her past mistakes have allowed her to become the person she is now. Afterwards, everyone goes with Iori to see her mother, where they both realize they had both made mistakes trying to make the other happy. After Iori's mother gains the encouragement to turn her ex-husband away, Iori gives thanks to everyone who made her who she is, and Yui apologizes to Chinatsu, promising to meet her at the next karate tournament. As winter vacation comes to an end, Iori starts to question if she truly loves Taichi.
