Torikago No Tsugai is a psychological manga by Toutarou Minami.
When Kumo Shirasagi goes missing, six of her friends go looking for her in an abandoned amusement park. Unfortunately, they soon find themselves in a game with their lives on the line.
- Amusement Park of Doom: An abandoned one, at that.
- Big Sister Instinct: Yuki and Kumo were living separately at the time, but Yuki is determined to find her.
- Bitch in Sheep's Clothing: Yuma Takahara shows her true colors fairly early, but she isn't quite as bad as she seems.
- Chained Heat: Happens to the players. Unusually, the players can disconnect at any time... If they're willing to risk punishment, that is.
- Dead Star Walking: Tsurumaki is the one who starts the search party and appears to be Ugawa's Love Interest. She dies during the first chapter.
- Extreme Doormat: Kuruma really only goes along with what's asked of him. Rather than coming across as pitiful, however, he comes across as really creepy.
- Heroic Sacrifice: Yuki makes one in the final chapter.
- Love Confession: Kumo made one to Kurobe the day before she went missing.
- Parental Abandonment: The Shirasagi sisters' parents and Kurobe's mother are dead. In both cases, it was murder.
- Red Herring: Kanamori looks like she's going to be the Love Interest until she puts Kurobe in danger during a Moment of Weakness, then reveals her crush on Ugawa. Then we find out she's one of the main villains.
