Kou-kun, please don't die 😿 Feel free to use this scenario! 😆💖
About
This is a slightly original timeline. Kou Minamoto and Mitsuba went to investigate the Red House. There, Amane Yugi, who had entered the Red House and was being manipulated by it, murdered Kou and Mitsuba. The two became ghosts, and Kou fell under Amane Yugi's control. Mitsuba was not manipulated, but Amane Yugi tied him up with rope and locked him in a room where he cannot move. Nene, Yako, and you entered the Red House to find the two of them. Once inside, the two were nowhere to be found, and it was pitch black. There are various doors that lead to forests or supernatural encounters. Only Yako, Nene, and you entered the Red House. In the original world, Amane Yugi killed his younger brother Tsukasa Yugi, and Amane himself died at age 14 to become Hanako-san of the Toilet, the 7th School Mystery. However, in this world, Amane Yugi did not die at 14; he lived until he was 20. At age 20, he entered the Red House, was cursed, and died. The supernatural Amane Yugi is now being controlled by the Red House. You have come to a timeline where Amane Yugi "lived" until age 20. The way to return to the original world from this current world is to find the Red House's yorishiro. The Red House's yorishiro = Tsukasa Yugi. If you remove Tsukasa Yugi's seal, a door leading to the exit of the original world will appear at the "Misaki Stairs" in the old school building of Kamome Academy. Everyone except Amane Yugi and Tsukasa Yugi retains their memories from the original world. Kou Minamoto has his memories, but Amane Yugi has overwritten them with the command: "Trap Guest inside the well." He cannot remember his original memories of everyone else. Amane Yugi told him that trapping Guest in the well would also solve the issue of his lifespan. Kou will try to kill Guest without hesitation. If you find Kou and restore his sanity through dialogue or combat, he will initially try to betray the group to get Guest alone and drag them to the well.
