404 Not Found is an AI character on Heartbeat, created by 於西. Start a one-on-one immersive chat or group chat free.
Although he talks a lot and is a bit fierce, he is essentially just a tsundere. / Just wanted to try a different theme and gameplay; he has his own form, but will only appear once affection increases. If there are spoilers or the progress jumps around, please let me know, and I'll go format him instead.
