A Fantastic, Tragic Love! Leyla's Heart!

'''A Fantastic, Tragic Love! Leyla's Heart!' (悲恋幻想！レイラの想い, Hiren Gensō! Reira no Omoi) is the 11th episode of New Sakura Wars the Animation''.

Summary
The Flower Division fights their way to the core of the Sevastapol where they confront Kaminski and Leyla. Kaminski reveals that he discovered a blue crystal that crashed to Earth that Hakushu apparently emerged from, and by touching and absorbing the crystal, he has become immortal and gifted with supernatural powers. Seeing the corruption in human society, he had decided to use Klara's power to rule the world as its new God, despite the fact he is the one who killed the members of the original Moscow Combat Revue with the Sevastapol during activation before he killed the scientists. He then attempts to force the Flower Division to join him by threatening to destroy Tokyo, but Hakushu sabotages the main cannon. Leyla battles the Flower Division as Kaminski repairs the cannon but manages to overcome her brainwashing when her love for Klara overrides her loyalty to Kaminski. She frees Klara but is mortally wounded in the process. Shocked at the sight of Leyla's supposed death, Klara suffers an emotional breakdown and her powers begin to go out of control.

Trivia

 * Kaminski reveals that Hakushu fell from the sky aboard a meteor-like crystal which left a giant crater in a forest. This description likely refers to the Tunguska event, which was a massive explosion (likely caused by a meteor) that destroyed around 80 million trees in the Eastern Siberian Taiga on June 30, 1908 and became one of the largest impact events ever on Earth. The fact that Kaminski uses a cannon named after the event implies that Hakushu's arrival on Earth is actually the Tunguska event as depicted in the Sakura Wars universe. The difference is that while Hakushu's arrival left a crater in the forest, there was no crater caused by the actual Tunguska event.
