   Summary

   Young Issei was upset with the recent move of his best friend, heart broken and downcast he makes a wish for a new friend. Never did he imagine he’d gain not one but several new friends and all because of a Sacred Gear he knew nothing about, one that has a rather intresting effect on his person.
