Kouga returns to take care of a new Horror, but afterward is attacked by a strange figure in a red mask.

Kouga and Leo are delivering Leo's Gouryuu to the western district, but after a battle it rebels and starts to turn into a Horror.

A Horror is running a casino and Kouga is sent undercover to find who is in charge.

An artist designs manhole covers that are then placed all over the city and become gates for Horrors.

Rei wonders if Kouga has told Kaoru about the seal on his chest; people are flocking to a weird looking tree outside of an old couple's home.

Leo abandons Kouga as he escorts an obnoxious elder Makai Priest to deliver a pelt.

An ancient samurai makes a deal with a Horror and is resurrected in present day. He is in search of a worthy opponent and finds Rei, who reminds him of the Makai Knight he saw as a child.

Kaoru and Kouga visit a play, with Kouga storming out before the end. After the show, the lead actor is killed by a Horror.

Kouga is off hunting a Horror and so Kaoru tags along on Leo's journey to find a Spirit Beast.

Kouga goes off to have all the evil ki cleansed from of him that has built up after each battle. After he returns, a Horror that can manipulate time appears and challenges the Golden Knight.

Rei stumbles upon a car accident that left no bodies, which means a Horror must be involved. During his investigation, he finds a familiar face.

After Kouga and Leo finish a training session, Zaruba spontaneously combusts. Kouga calls Jabi to help, who goes off to repair Zaruba, but the man in the red mask appears before her and attacks.

Kouga and Leo get word that a Makai Knight has attacked another Makai Knight. The two set out to help a familiar face.

During a run-in with a Horror, Kouga remembers the first time he encountered it during his training as a boy, and the friends he made at that time.

A Makai Knight is killed right in front of Rei and Leo says goodbye to Kaoru as she gets the final inspiration for her picture book. Rei and Kouga go hunting for the creature that killed a Makai Knight when they find the man in the red mask, and his identity soon becomes known.

Rekka appears to help Kouga deal with a Horror. However, the Horror has decided to go through Kaoru instead.

Kouga wants to figure out if Leo really is Red Mask; Makai Priests all over are turning on the Makai Knights.

It turns out that Leo is actually a Makai Knight. So who really is Red Mask?

The Makai Knights are all torn between giving up their armor and fighting Sigma, who has commandeered a train to the moon.

Sigma captures Kouga in order to use him to power Idea. Kouga's friends must then band together to save him.

Rei, Leo, Jabi, Rekka and Kaoru all head out to save Kouga; Ganon awakens and shows its true form.

Ganon has awakened. It's now up to Kouga, his friends, and an army of Makai Priests to stop it.

The Makai Knights defeat Ganon, but Kouga still must honor his contract with Gajari. On his way home with Leo, someone arrives to greet him.
