Phoenix Wright-ish detectiving, Kara no Shojo and its sequel are in this post. I don’t care for the series personally(I prefer a little less soul crushing in my murder mystery endings), and it barely counts as a game, but I will admit few VN’s require a walkthrough as much as the first Kara game does.

-Think Phoenix Wright, but replace the wacky with sex, gore, and truly crazy killers. Story is you are a detective 10~ years after WWII ended, and a bizarre killer has appeared. That and a high schooler wants to know her true self. Gameplay is like Phoenix Wright’s searching segments, you investigate and choose evidence and pick suspects, I am honestly only including it because how confusing it can be to play as the gameplay might as well just be extension of normal visual novel choices. H is all vanilla stuff, so no murder rapist scenes. The scenes are mostly shortish and just kind of pop up out of no where. Save contains all cg and scenes, and in game saves to each save point from a 100% walkthrough plus a save right before the true end epilogue.

This probably has an interesting story, and I know it builds on stuff from the previous game, but I couldn’t read it. The problem here is during the opening, before even the first investigation, is a 3-4 hour flashback with characters I had no reason to care about. I know they are important later, but I just got sick of them since I wasn’t there to read about them. The art and length of the game is better then the first and the gameplay is more forgiving, making me question having this here as the gameplay might as well just be a theme backdrop, and that’s all I can really say. Save contains all the save spots from the 100% guide and full cg/scene galleries.
