There's one problem in nailing the creature to the roof - even though bolstered by its Reiryoku, the blade isn't long enough. It only comes out few inches out of the beast's chest as it staggers forward - then, it leaps up with such force that the Scheele Sneider is torn from her grasp.
"Ugh. You know, that stings", the creature hisses, standing few dozen feet above Mayumi, as it reaches behind itself to pull the sword-like arrow from its back. The wound seals itself as soon as it's out. "And what's wrong with talking? I mean, why won't we just go and have a nice cup of coffee and forget about all this...?" The creature sounds sickeningly sincere as it says that - maybe it's joking with her?
