Alas, before Jin could reach his full potential, an Outer Demon attack left his soul crippled and his body weakened beyond repair.

Now, Jin lives out his days bound to the hospital bed with nothing but his brains to keep him company. Gone were the days when his peers hailed him as a genius as he struggled to even conjure a spell with his body falling apart.
