Protagonist: There are two - mansion owner's nephew Shiraishi Minoru and mansion owner's granddaughter Chisato. Minoru is quite an ordinary young man without distinct traits. Chisato is kind of tsundere and tomboy.
Story: It's not the murder that's terrifying but the way how it's done - mansion owner's neck was cut and he was hanged on a sakura tree upside down. Many old legends show up featuring ghosts and evil revenge spirits that kill only men and the whole game this atmosphere is kept up which is great. Mansion inhabitants are paralyzed with primal fear and police only comes to assert the deaths as suicide. Minoru's senior Kaneshima-san is the only one who is able to think sober and analyze the facts. He finds a hidden room inside the mansion where some kind of laboratory exists and tries to link the deaths with poisoning. Only couple of deaths seem to linked to poisoning and the others are done much more brutally with piercing wounds. So is it an evil spirit ravaging or are there several culprits? We'll find it out eventually.
CG: Cool CG in adequate quantity.
Sound: Full voicing. Even for both protagonists. One of BGM was irritating since it had one very high pitch moment deafening me and making voices unrecognizable, but lowering bgm volume helped. Also I'd like to notice that most of BGM are very lively yet old-mannered corresponding to Taisho era, so it's not a depressing game. Just with some atmospheric features.
1) It's not a theme, but rather a symbol. Blossoming sakura. It always had the most sweet reminiscences. Chiruhana treats it another way. Pink. Light red. Dark red. Red as carpet. It's the color of beautiful flowers that bring bad omen. Sakura demands blood. This symbol is repeated over and over with words an visuals and creates a specific atmosphere.
Overall comments: It was very difficult to make something good from such synopsis and game succeeded in that. Mystery remained strong till the very end and numerous details made the atmosphere really thrilling. The end was very satisfactory for me as every murder is explained. It's not my type of the game, but if you have a taste for good quality short atmospheric mystery murder story, it's much advised.
