Hoshi no Samidare

Synopsis

Mikazuki demands the knights go to summer training at the beach, though everyone ends up just having fun instead. Yuuhi sees Samidare has learned to use her powers to walk on water. She has been experimenting hoping to understand why all the knights' powers seem so random. Yayoi considers confessing to Yuuhi when she overhears him and Samidare discuss Samidare's intention to destroy the world. Yayoi decides to keep what she heard a secret. Later, Hekatombaion finally appears and all the knights gather to fight it, including Taiyo who is surprised Shimaki has kept his loyalty to Animus a secret. Animus abruptly appears and steals Yuuhi and Samidare, claiming Hekatombaion is a gift for the amateur knights only. Animus reveals that Anima, the spirit inside Samidare, is actually his twin sister and she created the knights to fight him. Yuuhi realizes Anima must be the one preventing Animus from using the hammer. Samidare attacks Animus, distracting Hekatombaion. Shimaki summons his own golem inside of Hekatombaion, damaging his body before he is destroyed by a combination of everyone's powers. Animus disappears again and the knights plan a seafood victory feast.
