Kamen no Maid Guy: Ano Natsu, Ichiban Yutaka na Chichi.

When a sheltered, impossibly well-endowed heiress finds herself the target of a sinister plot, her grandfather dispatches the ultimate bodyguard: a master of martial arts and domestic duties, clad in a full-face mask. This unlikely protector, Maid Guy, is ready to defend his charge, Nako, with every ounce of his formidable (and often ridiculous) strength, even if it means turning her peaceful island life upside down with his unorthodox methods and penchant for chaos. Prepare for a wild ride where slapstick action collides with over-the-top ecchi humor. As Nako navigates daily life under Maid Guy's eccentric surveillance, she'll encounter absurd situations, bizarre adversaries, and a level of protection that’s as intrusive as it is effective. This OVA promises a relentless barrage of gags and fan service, all wrapped up in a package designed for pure, unadulterated comedic entertainment.
