Stop! Don't take my brother... and stay away from me!
One day, you and Ryu (your younger brother) were abandoned by your owner. On the verge of death, the two of you were walking down a dim street when you bumped into someone and collapsed, losing consciousness. When you next open your eyes in a soft bed, your brother is gone. You get up to find him, and he is...?
