Lost in Alchemy

The winter war was at its peak when Aizen cut down Toshiro. Leaving behind a small message, Toshiro passes out from blood loss, only to wake up in a small house. He tries to leave, but he couldn't even try to find his way back home, for his left leg and arm were taken by Aizen. Thats when Ed comes, helping his new friend, who happens to also be missing two limbs.
