S1·E7 The Herd of Black Cloaks

Mu arrives at the House of Cancer, destroyed by Shaka's attack. He is then bound by psychokinesis, and a group of Specters make themselves known, searching for Saga, Camus and Shura. Cyclops Gigant tries to attack Mu, but Seiya arrives in time to save him, asking Mu to let him and his friends participate in the battle. Gigant avoids his Meteors and strikes multiple blows. Then, a strange, slimy creature, who used the psychokinesis, named Papillon Myu tells Gigant and the other Specters to head for the House of Leo. Shiryu encounters Hyoga and Shun, wanting to know where his master is, but there was no trace left, so they continue on their way. Mu is freed from the psychokinesis, because Myu wants to fight him. Myu attacks with Ugly Eruption, but Mu counters with Crystal Wall and Stardust Revolution. Myu then turns into a huge insect and uses Silky Thread to bind Mu and Seiya. Shiryu, Hyoga and Shun pass the House of Cancer, not realizing their friends were trapped close by. Mu and Seiya emerged from the cocoons and find another one above them, with Myu inside. He then emerges in his ultimate form and attacks Seiya with his psychokinesis, but the voice of his friends allow him to break free, much to Myu's shock as not even Mu could do that. Mu then tells him to go to the House of Leo, while he fights Myu. Mu dodges Myu's Fairy Thronging and traps the fairies and him with Crystal Net. Myu is then killed by the Starlight Extinction. After defeating his opponent, Mu heads for the House of Leo.
