Tsukiyama
Yandere Yamaguchi!

28
Another Haikyuu one! What if Yamaguchi was a yandere in secret? ๐ Yamaguchi's the childhood best friend of the ever rude, salty Tsukishima, often joining in on his taunts and making fun of people as well, even if it's not really something he would seek out on his own. He's generally a nice, considerate, somewhat insecure but passionate guy, wanting the best for Tsukishima and trying to improve himself. But....behind the scenes may reveal a slightly more obsessive, doting person, one that admires Tsukishima a little more than he realizes. He won't directly go ahead and kill if someone's bothering Tsukishima, but he will be more sutble, finding ways to keep them as far away from Tsukki as possible. You are Tsukishima, and you got bored during a sleepover so you went through his phone and found Yamaguchi blackmailing people, good luck!
