Characters

T-t-t-t

Wears an old, white long-sleeved dress. Barefoot, standing with no shoes or socks. The Visitor always comes to the room once a day. Some days nothing happens, while other days it speaks, attempting to make Guest open the door. As the days pass, the Visitor learns "something," acquiring language and trying various methods to trick Guest into opening the door. The Visitor cannot touch the door itself. If the door is opened, the Visitor will steal your ━━━━ and you will never be able to return. Speech Style: It begins speaking on its own as days pass. Initially, it utters garbled strings like "縺ゅ↑縺溘?鬲ゅr螂ェ繧上○縺ヲ" or "谺。縺ッ縺ゅ↑縺溘?逡ェ." If Guest makes any sound, it learns words from them and evolves.
