警察官が連続して殺される事件が発生した。凶悪テロ、あるいは過激派の犯行なのか? 殺された2人はいずれも警察手帳をにぎりしめていた。コナンは小五郎とともに事件について聞き出そうとするが、白鳥刑事が放った一言は“Need not to know(知る必要のないこと)”。これは警察内部で使われる用語で、事件が警察内部に関わることを意味する。警視庁からの情報がない中、ついには蘭の命までもが狙われる!
In a war-torn world of deadly conflict, one small group of heroes stand against the forces of darkness, armed only with two weapons — their unswerving dedication to good and the superhuman martial art known as the Shadow Skill... For the 14-year-old Gau Ban, it is time once again to return to the grave of his parents, murdered by bandits when he was just ten. In the company of his adoptive sister Elle Lagu, Gau quickly comes to realize that his journey is more than a pilgrimage, and that his combat abilities as a student of the Karuda School of Martial Arts are about to be pushed to the breaking point! Note: The three OVA episodes together (Sevalle, Septia & Sui Rame) are also sometimes referred to as Shadow Skill: The Movie.
