(the math is correct. dazai opens his hand, so the blasts can be released, and touches it almost immediately. the loud thud is his stone head rolling, some pieces broken, but it's good enough. next up should be his torso in three parts, and then to roll this shit down to the nearest trash and pretend this never happened at all.)

There we go! One piece down, three to go. Put the glasses on, if you don't mind! Fufu, I have to move your head again.
