Black★Rock Shooter (OVA)  

BRS OVA, ブラック★ロックシューター (OVA)

In junior high school, Mato Kuroi meets Yomi Takanashi. Initially, Yomi is taken aback by Makos straightforward personality, but they quickly become friends and spend time together daily. To signify their friendship, Mato gives Yomi a cell phone charm-a blue star, identical to her own. However, when the two enter their second year, their relationship changes as Mato spends more time with Yuu Koutari instead, a girl she met through the basketball team. As a result, the former best friends drift apart so much that Mato cannot find Yomi anywhere, as if she had disappeared entirely. Meanwhile, Black★Rock Shooter is on a quest to vanquish the Dead Master. Though opposed, these two share a connection similar to Mato and Yomi. As their stories intersect, it appears that Yomis disappearance may be linked to the blue star-shaped charm and the legendary gunslinger herself.
