A brief description of the manga Makenshi no Maken Niyoru Maken no Tame no Harem Life:
Fujinomiya Soujirou is transported to a fantasy world with only his Daisho (pair of samurai swords) in hand. The katana can talk and swiftly informs him that it is Hotarumaru, the legendary national treasure of Japan thought lost during World War II. The wakizashi is too young to have a voice, so Souji names it Sakura. This is the story of Souji and Hotarumaru’s journey through a new world as he seeks to achieve … a sword harem?
This is a half a hentai, super duper horny needs a bonk fantasy. I enjoyed it very much (ch 31 so far). There is a story, if you’re interested. It seemed to make sense. I recommend if you’re looking to fill a safe deposit box in your bank.
Seriously, though, it’s pretty degenerate, so be warned. You don’t have to read it for the naughty bits, there is a real story here, but you won’t enjoy if they bother you.
Rename title to:
Sword 4ucking 101! 
Artwork looks like the MC is hold a woman hostage.
Sword harem?
