The White Black Belt
While Leopard amuses himself by conducting a radio show, Kazane is concerned that Takane's reports have stopped flowing and orders that things be played by ear while Honoka shows Akiha and Itsuki the St. Artemis criminal corrections facility on the Moon where a part for Leopard is kept inside a perimeter of alarms before leading the way into the facility where she promptly loses her way. UL quickly locates the group's destination but accidentally instigates a prison riot that brings Bougainvillea and Mintao into the mix. While Akiha tries to swim out of the stampeding prisoners, Itsuki and Honoka encounter Sakura's personal bodyguard that wishes to befriend the pair; a brief but fierce battle gives way to an encounter with the charming and affectionate Sakura. Akiha rejoins the group in time for a video feed depicting Takane as Aleida's prisoner and rushes off to the rescue with Honoka and Itsuki right on her heels. Aleida stalemating Honoka gives way to Leopard's sudden arrival -- and Nerval's awakening from a protracted estivation that has amplified a fierce long-standing vendetta.
