well im starting to think they were sent back in time now that they found that charred picture that mina has which is exactly the same

There is either time travel involved or Mina is some kind of clone. But if time travel is involved...I'm betting their in the future not the past. And since they found the burned drawing that means that someone will make it back to their original time to deposit that picture. Anyway, can't wait to see what happens next!

I wonder what secret Nishikiori knows that Akira's group doesn't know.
It seems like he'll be a force to be reckoned with again.
I'm guessing that the 3rd time's the charm, and he'll die after he tries fuck shit up again.

Going by what the final page says, the upcoming events are probably going to be awesome.

1) Oomori is getting annoying. She should really just spill what she knows about the monument, because as far as I'm concerned it is definitely a grave for Isurugi Miina. Yes, she might add to the confusion but then it can be a new lead too. I don't dislike her character but that part of her really annoys me.
2) Nishikiori is still up to something, but I really hope that the author don't make him become the main antagonist yet again. This chapter proves that there are still some dogs of Nishikiori on his side, and he will be the double-edged sword. He definitely knows something that Akira and co. doesn't, while proving to be capable of dangerous things anytime.
3) Rion got jealous again, haha. Guess she is still not used to Akira's popularity. But she should know that Akira pretty much only has eyes for her Too bad we never had another kissing scene since the back-to-back arcs very, very early into the series. The last part with AkiraxRion relationship development was before they entered the pyramid way back, where Rion was willing to let Akira see her boobs.
4) The last page already foreshadowed something that will make them lose all hope at the last tower, I'm pretty sure the people living there are already all dead or something, because they are in the future! And this is what our friend Nishikiori knows.

well it could also be that she was there and then died and then they used the cloning stuff to clone her but she has no memories so they tried fixing that and now she is stuck there again with just some possible repressed memories that were programmed into her tho this is just a theory
since u know there was something there looking like a grave with her name on it

for 1 i think that she is dead and the current one is a clone since the hav the tech for it tho idk how that gonna help but i got a feel like thats whats gonna be revealed if anything she might hav info on this island after her memories are restored

on 2 ya i also hope they dont make him the main bad guy again and when he duz try to take over that he is tooken out rather siple and it leads to something way bigger then him

on 3 ya i like these scenes i feel like since the series has been back to back with nice arcs that it was starting to lack these scenes that are rather fun and help since i wish there was a bit more development with the couples and such cuz i dont want the series to be over and them just hook up randomly id rather like a nicer lead up
and for 4 ya im excited for what is planned for the last tower since they are making it to where they lose hope so they must ind something big but it also has to lead to a tiny bit of hope since they cant just be stuck there with out understanding anything
i would like a proper ending even if it isnt the happiest
anyway sorry for my spam i just liked what u thought about it and wanted to reply off some stuff i thought about it
