Manga Directory -- O

Due to his extreme NTR (Netorare - cuckold) fetish, Asitaba Kimikage (明日葉君影) has become a man who cannot feel excitement in love unless NTR is involved. No matter which girl, which situation, or what kind of romance, he always ends up thinking: \"What if this were an NTR situation?\" This twisted way of thinking has made it impossible for him to have a normal romantic relationship. However, one day, Kimikage meets Asahina Satsuki (朝比奈紗月)—a girl who is pure-hearted, honest, and completely unrelated to NTR. Her genuine kindness and determination slowly begin to make him realize his true feelings: \"I want to experience real love.\" Will Kimikage be able to overcome his distorted fetish and find true love, or will he once again fall into the endless cycle of his own delusions? A hilarious yet heartfelt story about self-discovery and breaking free from one\'s own obsessions!

Otoko Ippiki Gaki Daisho

The plot of the series revolves around Mankichi Togawa, who at the start of the series is a single delinquent student with one dedicated follower. Like many later iconic shonen protagonists, Mankichi's power is his ability to appeal to the others around him who join his cause (sometimes only after first losing to him in a fight). Join Mankichi as he fights other delinquents, dangerous criminals, and even juvenile detention camps! Historically, this is Weekly Shonen Jump's first major hit, the title that got their magazine to sell millions. The authors of both Saint Seiya and Fist of the North Star have both stated in interviews that Otoko was their inspiration to get into the manga industry, and it was one of the first shonen manga to get its own anime. While it may seem insignificant now, nearly every Shounen Jump manga out there owes its existence to Mankichi.
