Kyou Kara Ore wa is what I would consider one of the classics of gag manga. How old is it? It was serialised in the 1980s and despite that, its brand of humor is still very relevant today.
Naqua-Den is by one of my favoured manga-ka; Mitsunaga Yasunori, who also did Princess Resurrection and in many ways can be considered a spin-off sequel to the aforementioned manga.
Okay, previously I recommended a new work by this author; Otogi Taisen Phantasma, so I thought I'd recommend his previous work. Which was what made me interested in his works in the first place. If I had to describe this story, it would be brother with sis-con gets involved with a secret underground fighting tournament that involves clones of his dead sister.
It's rare that I actually recommend a manga, but this one's pretty good. It's also but the author of Kyousou no Simulacra, which is also good. Basic Summary: Guy discovers he's a prince of a magical kingdom; and now the King since his father died recently. Some people want to protect him, some people want to assassinate him.
It's not often I talk about a manga or Light Novel; partially because I don't like to give reviews on incomplete things most of the time. And most mangas/LNs take ages to finish. However, this is one of those exceptions.
