Love how takashi has double like personality best assassin ever.
Love how they fall in love but don't need words to say so. The stray dog becomes owned. Love how chiaki is short but a great fighter and miki is just a "fag"
They follow the line and fall in love become a great couple and even die old together super cute story
Shiro a abandoned kid becomes one with the towns stray cats but is loved by all especially iichi who cares for him the most.
Its a crime to leave this manga as a one shot
There should be more of this
