The Blood of the Katana

Kasai has done everything he can to support his sister, Ayumi. After witnessing both of his parent's death, he has pushed aside the trauma from those experiences to push him and his sister forward. In his small notebook, he keeps and writes poems from experiences and feelings he can't express. As his girlfriend, Vanessa comes, those poems get lengthy, but everyone has a weak spot. When it's found, broken even, those stanzas, those lines, become shorter until there is none left. One poem turns into one stanza, one stanza becomes one line until it's gone. How much pain can one go through before the ink turns into blood?
