Tsukasa Matsuzaki likes to get really really really fancy with his titles so fancy that if you put them in English they really don't make any fucking sense if you don't know japanese.
First off this is the 3rd (and final arc) of this two from killing the crow series, so the title has the nice kanji for 3 in the title (三）the previous ones before it had of course
Correction: only the 2nd arc also follows it there are 4 or so stories before that don't use this clever titling style.
Secondly! This title is also a clever reference to past present and future existances (as this is what it directly translates to) This is referencing how Hiroshi is basically a woman for all intents and purposes in every portion of this series but at the same time he's a guy because otherwise you wouldn't be reading this, right?
Also there's the whole thing about him thinking he's going to get pregnant and Hato making him his woman too.
So to summarize, he is using the fact that there are 3 arcs to this story to at the same time have titles that directly correspond to the plot of each arc. While still functioning as just simple 1,2,3 numbers so that's kinda nifty. Enjoy!
Oh and I will be translating the 2nd arc in between this one also Priapus 3, Kagura Dance and rugby thing will have to fit in there somehow oh boy next week will be a doozy.
This is all ranting so I'm just going to keep it seperate.
The following his has nothing to do with explaining the comic but after reading all of these and this is once again just my personal preferences but damnit I hate Hato and he needs to get fucked. This is usually the case for all of the "tops" of Tsukasa Matsuzaki's works sometimes exceptions can be made, like that size difference comic I translated sometime back that I really need to get around to reuploading to make the point clear but anyways. The guy is hot don't get me wrong but I just have a thing for knocking characters like that down a peg, a very sadistic thing.
also whoops I deleted my chat box on accident it shall be back soon.
