Akane does this 200 times, every time it start from june 4, but only 21 years ? So the time June 4 is also a fake ? But if this is fake then how they control the weather ??? Like in december, it will be cold and snowy ?
I don't know what they plan but let the girl go through the lab just so, what if they just build a bomb (or grenage like Sayaka have) to explode the lab ?
There is the part about the whole Izumi house gone, if everything is experiment then it is extreme weird.
I feel like this story is not planned from the start, only get extend after each chapter. Like the first chapter, they don't even focus on Akane, they are stabbing themselve (and even stab Izumi first), if the chip is manipulate the behavior to attack Akane, then stab the brain will shut down the body too, and there is noway, that mini chip can even control the whole body to be in the zombie state like this. I think the author, in the beginning, planning to do a fantasy/supernature series with curse and time travel, like how it really focus on the journey book in the beginning, then in vol. 2 and vol. 3 it just brute force to become sci-fi, making it expose many plot hole. But still, this is good yuri series i have seen for awhile.
