Shin's going to want emotional healing. He knows that for some reason he's been feeling desperate for love in all the wrong places, but it's currently only a half-formed realization. The healing will hopefully help mend SOME of those wounds (Since there's so many it would make it pretty OOC if they just all went poof) and let him remember at least that there are people back home that he loves and love him. It will reveal a lot of his memories about his current canon relationships, and about the running theme of a lack of any real kind of love until he joined Blast. Details not involving Reira and Nana K. (Hachi) will be fuzzy still, but he'll remember he's in a band, in love with someone from their rival band, and how much his friends in the band are like his family, and specifically how he wishes Nana K. was his mother.

It will likely cause a short term worsening of things for him, but also give him the ability to bounce back and really fight, since at the moment, the only real reason he has to fight the label is he hates feeling like a puppet.
