Shining Tears X Wind

A group of students are concerned over mysterious disappearances happening all around Tatsumi Town. A being from another world complicates the lives of two students and accidentally sends them to another world.

Souma and Kureha become more familiar with the dream continent, End Earth. As they are greeted by the people of the Seiran territory, word of a battle against the Philias territory would later thrust the two students into battle. The two are shocked when they realize that their enemy is their own friends, Kiriya and Seena.

When Souma realized that the enemy they are battling against is Kiriya and Seena, he begins to fight Kiriya even though they are friends. When Kiriya refuses to fight seriously against him and tries to reason with Souma, telling him that the people of Seiran tricked him, Kureha is suddenly used as a hostage by Shumari. The group then comes together to rescue Kureha.

Souma's disappearance troubles the group, but they soon realize that they have an even bigger problem. They encounter an old friend who is in control of a massive army, proclaiming himself Emperor of Baelgard. Meanwhile, Souma meets Zero face-to-face.

During the battle between Kiriya and Xecty, one of Saionji's four guardians, an earthquake occurs, causing both warriors to fall into a cavern, trapping them. Meanwhile, Souma and his new group comes across a Baelgard camp, where elves are turned into mindless soldiers for Baelgard.

A berserk Xecty escapes from her cell, tracks down Kiriya, and attacks him, but she is retrieved by Hiruda, who temporarily reverts to her original personality after her alter ego's soul blade is defeated by Souma.

Souma attempts to negotiate a peaceful settlement between Kiriya's and Saionji's parties, but fails. As Kiriya and Saionji face off in an all-out war, only Xecty's sacrifice can stop them, but this act has unforeseen consequences.

After Souma is rescued by Zero, Zero reveals his past as a member of Weissritter and tells a story about his life. At the same time, the Luminous Knights and Jin-Crow arrive at Valeria and meets Mao.

Xecty's death prompts Killrain to release an immense dark force, which also causes him to go mad with vengeance. He starts his destruction by controlling the Baelgard elven army, and goes after Saionji. Before Saionji engages in battle with Killrain, he entrusts Souma with a capsule containing the world's hope. Meanwhile, Mao encounters Blanc Neige, and furthers her search for Zero and Souma.

Souma is unexpectedly reunited with of all his friends. The reunion begins with Souma leading the depressed Kiriya to meet the world's hope. Souma and Mao catch up and talk about Zero, who at the same time secretly overhears their conversation and decides to depart from their presence. Later, Mao and Souma fight together against Zeed.

Lassi guides the combined group to meet the elf Kiriya saw in his dreams. Xecty becomes the priestess of the tower of the wind, but Killrain's actions prevented her from completely releasing the tower's power. The group now decides to storm Killrain's place and liberate Saionji, whose power prevents them from restoring the tower of the wind's power.

After arriving at the destined place, the group splits up, focused on rescuing Saionji. After fighting their way towards Saionji, the group is unable to pierce the barrier surrounding him until Hiruda arrives and tries it herself. Meanwhile, Killrain is revealed to be possessed and becomes Er Fahren. Later, each of the three Soul Bladers discovers who their 'Holy Grails' resides in.

By combining the power of the three Ultimate Soul Blades, the soul bladers are able to defeat Er Fahren and liberate Killrain's soul. Killrain and Celestia decide to be sealed behind together. Saionji and Hiruda decide to remain behind to help restore the forests of Baelgard. Using the power of his Ultimate Soul Blade, Souma is able open the path to his own world.
