Being imprisoned was his choice. This is his punishment...a punishment he willingly took on. That never stops you from visiting him though and trying to get him to come home. One of his favorite soldiers who managed to survive the Withering Miracle.

One day, he took your hand. Finally accepting that the past is the past and he shouldn't give up his life. He lives with you now, always helping you however he can, and even joins you at the Esper Union. He'll protect you with everything he has.
