GARO: Heir To Steel Armor

One night, the magical knight Ryuga Dogai who holds the title of "Golden Knight Garo," annihilates the horror Shauras. Then the magician Koyori appears. She has asked Ryuga for help in order to prevent the opening of the Gate of Destruction, the oldest gate where Horrors first appeared in the human world. Guided by Koyori, Ryuga visits Claire City, the city where the Gate of Ruin is hidden, and senses an evil spirit lurking in the bustling crowds...

The true identity of the Hagane, that bisected the Horror Regrege, was the Makai Knight Souma Shirahane. "This is my city", Souma says, checking Ryuga Dougai and leaving. Then, Mutsugi, a Makai Priestess, appears. She apologizes for Souma's rudeness and tells Ryuga of her orders to protect Creacity, which is in danger. At the same time, Igusa, Ron, and Obi, the Three Swordsmen of Agora whom Mutsugi had summoned, arrived in the city.

With the influence of the Gate of Destruction growing stronger by the day, Ron and Obi are hard at work training in preparation for the next crisis. Souma Shirahane, on the other hand, is alone in his frustration after witnessing the "Flash Sword" unleashed by Ryuga Dougai on a Horror. However, the situation is critical. Igusu asks Souma to protect Creacity with Ron, but Souma stubbornly refuses. Instead, Souma offers Igusu a proposal.

Godou Shirahane is involved in the anomaly of the Gate of Destruction.... Souma Shirahane drew his sword in anger at Igusu's statement. As his actions cause a stir, Souma admits his own faults as a Makai Knight and entrusts his Makai Sword to Mutsugi. Mutsugi, troubled, calls up Ryuga Dougai and confides in him about Souma's trauma. Meanwhile, new disturbing signs begin to emerge in Creacity...

An office building that has turned into a hive of countless Horrors as employees are possessed one by one. Ryuga Dougai, Koyori, Mutsugi, and the Three Swordsmen of Agora gather to address the unusual situation. Do not let the Horrors get out. It was Ryuga who stopped Mutsugi, who was about to place a ward on the building under the direction of Igusu. "We can't leave him out of the loop right now. This city needs Souma!" What decision does Souma Shirahane, who is struggling alone, make?

The "Night of Dawn", which is said to open the way to the "Sekigan Forest" once every three years, finally arrives. Ryūga Dōgai and Souma Shirahane enter the forest and encounter the spirit Rauru. Rauru offers one condition in exchange for the location of the "Stone of Eternal Darkness", the key to the Labyrinth of Arvis. Meanwhile, Creacity is a glittering city at night. There, Naomi, a employee at Crea Hall, looked at the brilliant dancers with envy.
