Adekan manga

Adekan summary:

Shiro, a laid-back and absentmindedly seductive umbrella craftsman, is (surprisingly) a close friend of Koujirou, a hot-blooded young police officer who stands against all things undisciplined. With their mutual knack for attracting trouble, the pair soon find themselves involved in a bloody and erotic thrill-ride in their off-kilter town full of equally off-kilter people. This action-packed jack-of-all-trades manga will have you swooning at its sexiness and leave you more addicted than opium—guaranteed!
