Sexy Commando Gaiden: Sugoi yo!! Masaru-san

Transfer student Fumiya Okometsubu hopes to make ordinary friends at Wakame High School, but his first connection is Masaru, an eccentric martial artist with boundless enthusiasm. Returning from training, Masaru champions a bizarre fighting style that relies on bewildering opponents and destroying their concentration.

Determined to build a club around his method, Masaru pulls Fumiya and an assortment of classmates into exercises and competitions unlike anything in normal school life. The more Fumiya tries to understand his new friend's logic, the further he becomes entangled in a world governed by Masaru's unpredictable ideas.
