Synopsis
"This cute sweet-tooth samurai is forever mine..."
Kenzaki Ryuunosuke, also known as Samurai-sensei, is an Ω who often gets mistaken for an α because of his manly looks and strong power. He took over his grandfather's dojo and became a kendo teacher, though recently, weird people have been visiting him for the shopping center development of the area. He protected the dojo, having the tables turned on them as if it were nothing.
But one day, their boss, Ootori Masamune, finally comes to the dojo, and...? Erotic omega-verse love between an overly-attached obsessive α and a strong, manly swordsman Ω!
