Play My Best Friend, Yui. Online

What awaits you in Yui

A psychological horror yandere visual novel by Ruchyan. You play a high schooler whose best friend Yuki has gone missing, and the new friend who appears to help is the one you should worry about.

01 · MISSING

Your best friend stopped texting back

After school, you find that Yuki, the only person you actually trust, has gone quiet. The signs around her house are stranger than absence should be.

02 · YUI

Someone very kind wants to help you look

A classmate called Yui offers to help. The smile is the right shape. The timing is too convenient. The way he watches you is the part that does not fit.

03 · PRESSURE

Curiosity and caution are both dangerous

Curiosity moves the investigation forward. Caution keeps you out of the basement. Both of them change the day you are having, and the way Yui is watching it.

04 · END

Fifteen ways to leave the afternoon

My Best Friend, Yui. has 15 distinct endings, including a secret one only the community knows the path to. The path you take depends on how you respond to the parts of Yui you should not enjoy.

How to play

1. Press Play to launch the Ren'Py web build. Sound is part of the design, so leave it on.
2. Treat every Yui reply as a small commitment. He notices tone, and several endings open or close on a single sentence you almost skipped past.
3. Use the in-game save menu before the obvious branches. The game is short, but the route order matters, and a quick save lets you take the path back.
4. Re-read without Easy Mode after one full run. The visual novel is built to read the player as much as the other way, and a clean second pass sharpens what the first one let pass.
