Hmm, considering the way their powers work, perhaps Hana or Od were the failures to each other. Oiran Trooper tears space apart whilst Od seems to be able to manipulate space. I do also wonder that if all of them came from the dark side, if there's perhaps a truly perfect version of them that...
Finished reading it, and yeah, the flaws are fairly evident. But this was still quite nice to read and still way better of an ending than many other manga that didn't get cancelled.
If she's borrowing "time" instead of her own future power. Maybe the drawback would be her not being able to use her powers at all for some "time" in return. At the very least I feel like it probably won't make her sleep again since she's no longer interacting with her future in the same way.
Fully agree with you, the paneling is so fkn peak. On the topic of Touge Oni, that too is a great read and I recommend anyone that hasn't done so yet to check it out.
Thanks for the chapter, I kinda forgot about this for a bit. But now that I read it I realized that there was a hole in my heart only Hayasemaru could fix.
