Are there any Katekyo Hitman Reborn doujinshi that aren't yaoi, hentai, or shounen-ai? Since KHR is a shounen series, I don't think there would be any doujinshi that would be yuri or shoujo-ai but I can't say that for sure. I really like KHR and would be interested in reading doujinshi related to this series but I really can't stand yaoi, yuri, shounen-ai, shoujo-ai, and most of all hentai! Most doujinshi seem to revolve around this genres so I tend to categorically avoid doujinshi, so if anyone knows of any KHR doujinshi that don't involve these genres I'd appreciate it.
