Story
Just because you’re old doesn’t mean you can’t throw hands! Octogenarian Kaichi Takemura is a master of aiki-jutsu, a martial art that specializes in redirecting physical force. Alas, time soon catches up with the spry old man, as do the perils of an aging body. With a terminal cancer diagnosis and only two months left to live, Kaichi stares out from the hospital with nothing to do but wait for the end of an unfulfilling life... Until the moment he coughs, blinks, and finds himself transported across dimensions along with his resident nurse!
