First off, I suck at writing reviews, so this will probably be a sucky one. BUT I'm going to try my best to summarize the workings/concepts of the world first (...from what I understand anyway, because my Japanese isn't the best and I skipped quite a lot during the exposition-y bits) because it's pretty interesting and might tempt other people to play this game too. Obviously there'll be
spoilers for the route summaries so here's a warning in advance for that.

Image stolen from the official site because I'm lazyBasic Plot: This game is set in a city named Glazheim (グラズヘイム) where humans and these type of people called Hanki (半綺) lives and apparently there's some kind of silent war going on between the two races. The main girl, Hijiri Futaba, is the daughter of the head of this organization called Freikorps (フライコール). Not that Futaba knew anything about this since she always thought her dad died in a car crash ages ago. Then one day she comes home to find her mom missing and their apartment a mess and like all good shoujo manga cliche, she's about to be attacked by these group of thugs, when a pair of twins, Reimei and Shirou, come to her rescue. They were apparently sent by her father, who only truly recently passed away to protect her and escort her out of Glazheim or something but apparently Reimei has other ideas and would rather have her succeed her dad as the head of Freikorps and fight against this other ~*evil*~ organization called NEDE.
( Bleed and Revive (Warning: lots of TL;DR) )...wow that was long. I'd have included a CG pack here but I'm too lazy to rip the CGs, or actually finish Wataru's path so I didn't. But if you don't mind the incompleteness and would like me to upload it anyway, just leave me a note \o\
