I really love this picture drama. Maybe because I'm a gamer as well, and I like the Haikyuu!! characters in RPG style. This is an extra, the whole 3 episodes are about 12 minutes, so don't think, that it adds anything to the original story. I think the implementig is amazing. Five Haikyuu!! characters: Hinata Shouyou, Kageyama Tobio, Iwaizumi Hajime, Takanobu Aone and Kozume Kenma are join forces to fight against the evil and tyrant king: Oiwaka Tooru. The DVD was originally bundled to the Limited Edition of the Nintendo 3DS game: Haikyuu!! Tsunage! Itadaki no Keshiki!! so the story also gives a kind ofgame-feeling. The characters are like in a Fire Emblem or The Legend of Zelda game, the milieu is like in a NES game, the music is also 8-bit, so, it's like in an 80s game with the anime characters on the side of the screen. The music is like in the best NES games, which gives great feeling to the OVA. So, I like it very much, as a Haikyuu!! fan as a Nintendo gamer.
