Just read Qualidea and so far I'm interested, the same ideology but a different approach. That's what it feels like anyway, maybe I'm just pretending to be smart. How many chapters are there in volume 1? And I should read it like Haruma - 1, Haruma - 2 and then Yuu - 1, right?
Yep, you should read the first chapter in that order.
There are eight chapters and an epilogue in volume 1.
