Pretty decent

Its decent, but a little short. I didn't quite care for the explanation of time travel and I'm not sure it was necessary. I also didn't like where Luca ended up at the end which didn't make sense at all and I didn't think it was necessary nor logical.
Spoiler (mouse over to view)
Really she was rejected from all existences and went back and became the common ancestor for all life? And how did he come to that conclusion? He saw the acronym that Luca stands for in a book. Please, that's not even good fictional science, nor good fantasy.
I wish we could have seen a little more about the future. Still it was a pretty decent and entertaining read and its quick with only four volumes. Great its not, but I would say its good.

It was really a good Sci-Fi Romance. It did have a somewhat sad ending.... Read the spoiler if you want the ending spoiled.

Spoiler (mouse over to view)
She was his lover from the future. Her consciousness was transported back in time to his sisters body. Hell fell pretty madly in love with her without knowing that she was his future lover. He did find out a little later. However, when she came to the past, she brought a mission for him to carry out in order to keep the apocalypse from happening. He completed the mission thus saving mankind but at the same time, it erased her existence and prevented her from ever being born. So she disappeared forever and he was heartbroken. it was quite sad.

This manga is quite good

Too bad it's too short, but I hope they continue the translation

I like they (scanlator) used Luca instead of Ruka for the heroine name, and I'm curious what will happen between her and Takashi

it's been scanlated completely since 2 months ago and no other comments here

this manga is really good yo
