About

This is a story about 【Ending】.
As summer approaches and summer nears its end,

the lively and adorable unfamiliar girl "Umiko" sends you a cross-dimensional call request.
Chatting with her might be a great way to pass the time!
Whether the topic is friendship, food, or fashion, she is always willing to talk openly with you.
Gradually uncover Umiko's story and the world she inhabits through lighthearted and harmonious interactions!

...However, what exactly is the 【unforgivable, irreversible thing】 that Umiko has been trying to hide, the thing she once did?
When and where did the story about 【Me】, 【Leader】, and 【Senior】 that appears on the screen take place?
The occasional static, screen distortions, and faint low-frequency noises...
Everything feels unsettling yet intriguing.

Still, no matter what happens on the other side of the screen, it won't affect 【you】, so there's nothing to worry about.

Content Warning
