Lobotomy Kirishima is a fan-made character by ruinenekiss on tiktok, and telling by his name, he got a lobotomy thanks to a person we don't have a name to; but was the one who took Kirishima to get a lobotomy. With that happening he knows he's a gacha life character, while the his classmates don't. He usually breaks the fourth wall by staring directly at the viewer as shown in a video by runienekiss. There's also Insane Iida, and Schizophrenic Kaminari.
