No one quite knows what’s going on since Hao attacked the base, the place where the road to the Holy Ground of the Stars is. The X-Laws make their way to a doctor for Jeanne-sama. When Millie asks Marco where Lyserg is, he tells her that Lyserg is no longer with them.
Ren demands that Yoh fight him, to the surprise of everyone. Jun backs him up, asking him to listen to Ren. Ren and Bason prepare as Yoh calls Spirit of Sword. Ren asks what Yoh is doing. He replies that he will fight with everything he has. Ren retorts if that’s true, why did he just reducing his oversoul. Yoh tells him that he thinks this form is his true self. With a slight prick, he bursts Ren’s oversoul. Ren then calls forth Bushin. Yoh tells him that when his oversoul is big, his furyoku will be limited. Ren attacks, but Yoh stands calmly and blocks. Ren starts to understand that bigger OverSouls are draining and reduces his own. They fight head to head this time until Yoh is pushed backwards. He tells Yoh, that they still aren’t strong enough. Until then, they both will lose.
Silva leads the group to the Forest of Hairas, the place where Great Spirits are, and the mouth of the Holy Ground of the Stars. The Great Spirits live in a different dimension, so the group continues forth.
Anna, Pirika, and Tamao watch over Mikihisa as Manta talks to Mosuke and Morphine through his laptop. Soon, Lyserg walks into the cave and Manta anxiously follows. Anna uses this as an excuse to follow Yoh, but Yomei shows up and tells her there’s something she still needs to do.
In the forest, Yoh and the boys are attacked by a large beam. When the smoke clears, they are standing on a circular plateau. Horo Horo tells everyone to leave as he fights alone. The shaman continues the Beam as Horo Horo defends. Soon, Faust and Ryu jump in the fight as more of Hao’s henchmen show up. Yoh goes off with Silva and Karim to find Hao.
Manta comes across Lyserg eavesdropping on the rest of the X-Laws. Marco overhears the commotion and slaps him, asking him why he’s with Manta. Kevin tries to explain that they will die fighting the X-Laws. Mine-san takes Lyserg’s Angel Zerual back. She just wants them to watch. Soon, Hao shows up. The X-Laws call their Angels as Hao checks his meter: 10,500, 8300, and 9700. His Sprit of Fire then takes them all out.
The rest of the priests ask Zinc why he, as a 10th priest, went over to Hao’s side. Jun and Ren fight as one of Hao’s henchman calls forth Lucifer. Ren stands ready to fight, telling Yoh to go.
Mine-san falls defeated in front of the X-Laws. Kevin volunteers to fight next. Hao crushes him, using his Spirit of Fire. They are willing to sacrifice themselves to find out Hao’s secret. Another of the X-Laws borrows power from three angels to form a protective barrior. He assumes that Hao’s medium is the atmosphere’s oxygen. Fire burns on oxygen, so if he can burn all the atmosphere oxygen, Hao will be defeated. He forms a protective barrier and throws a Hand Grenade X to burn up all the fire. All the oxygen is consumed, Hao still stands. Mine-san steps forth with Zuriel and punches Hao’s spirit, which has changed from fire to water.
Yoh finally shows up, as Morphine goes over to Lyserg. Hao captures the souls of the 3 fallen X-Laws and allows his Spirit of Fire to consume them. Lyserg is pissed now and calls Morphine to protect them and the angels. Morphine consumes them in angel form, as Jeanne-sama steps out of the Iron Maiden to thank him.
Hao then calls to the Great Spirits.
