Dog Days

Biscotti's army fights a losing battle with the forces of Galette until Cinque manages to hold off the enemy's offensive fighting alongside Captain Éclair Martinozzi. However, the two must join forces to confront Galette's commander and most powerful warrior, Leonmichelli Galette des Rois.

The battle ends with Biscotti's victory, but Cinque learns that Millhiore was not aware that once he was summoned to Flonyard, he cannot return home. Meanwhile, Leonmichelli's younger brother, Gaul, learns of his sister's defeat and is eager to face Cinque in combat.

Gaul's special forces, the Génoise trio, kidnaps Millhiore and he challenges Cinque to a duel. Cinque, Éclair and chief researcher Ricotta Elmar come with a plan to storm the fortress where she is being held to rescue her in time for her victory concert. Heavily outnumbered by the enemy, Cinque and Éclair manage to turn the tides when the freelance knights Brioche d'Arquien and Yukikaze Panettone come to assist them.

Cinque and Gaul's duel is interrupted by Leonmichelli who reprimands both for ruining Biscotti's victory party. Almost running out of time for Millhiore's concert, Cinque comes with a plan to return the princess to the castle for her performance.

Cinque learns from Millhiore how she used her stargazing powers to learn about him and why she chose him as her hero. Meanwhile, Leonmichelli confirms by using her own stargazing powers that an ominous fate awaits them.

Desperate to change Millhiore and Cinque's dreadful fate, Leonmichelli challenges Biscotti for another battle with each country waging their most sacred treasures on it. Millhiore reluctantly accepts the challenge, unaware of her true intentions.

The day of the battle comes and it does not take long for Millhiore to confirm her suspicions about Leonmichelli's behavior and she joins Cinque and Éclair to storm the fortress where Leonmichelli is stationed to confront her. Meanwhile, Brioche and Yukikaze feel that a strange presence is approaching.

Bearing both sacred swords, Millhiore reaches the top of the fortress to confront Leonmichelli, who trembles when she realizes that her actions are leading the princess to the same destiny she fought so much to avert, when a powerful and ominous creature appears before them.

The monster grabs Millhiore and flees the fortress on a rampage. Cinque struggles to reach the princess before she is absorbed by the creature, while she learns that the monster is actually a fox deity cub whose body was pierced by a cursed sword.

Cinque and Millhiore manage to subdue the monster and restore the fox cub to its former self. Yukikaze offers herself to take care of it and a huge concert featuring the princess is held to celebrate the end of the hostilities between Biscotti and Gallete.

At last Ricotta and her assistants come with a way for Cinque to return home. However, she finds that by doing so, not only he will forget all memories and experiences of his time at Flonyard, but he will never be able to come back. Upon learning of it, Cinque asks Ricotta to not tell the truth to the others, as he does not want them to send him off with a sad face.

Just after Millhiore confesses her love for him, Cinque is sent back home and has no recollecions of his days at Flonyard. However, Ricotta learns that a way to make his memories return and be summoned back is possible, thanks to the possessions he left behind as a keepsake to his friends and the promise he made to them that he would indeed return. Upon regaining his memories, Cinque renews his vow to visit Flonyard again as soon as possible.

The hero of Biscotti is back and this time he is not alone, he has brought 2 new Heroes to compete in war!

The current ruler of Pastillage is jealous of those competing in the war. After she catches a glimpse of Rebecca, she is determined to make her a Knight.

Rebecca has taken to the skies and Pastillage has official joined the war. Her skill as a mage and playing video games quickly turns the tide of the battle.

With the war games over each Princess has gone back to their respective kingdoms. Sink, along with friends, are spending their time training in counter-monster skills.

Couverte and Sink have accidently released the Demon King from his sleep. Even with all the heroes powers combined he proves to be a formidable enemy. Only the Hero King can stop his rampage.

A seal in a cave of monsters has been broken leaving the Heroes of old to call in the new generation.

The festival is in danger due to the abilities of an unexpected guest.

A new war between the nations is about to begin but Biscotti's Captain of the Imperial Guard is having problems that will lead Biscotti into ruin.

One on one battles continue with Becky vs. Millihiore, Rebecca vs. Hina, and Sink vs. Gaul. A wild card appears to shake the battle up even more.

The Union Festival comes to a close, and Millihi and Sink take some time to relax at Yukikaze's house. But things take an unexpected turn when Millihi finds a strange crystal, and the three are engulfed in a blue fog...

Wanting to get a gift for Rebecca, Couverte along with Rico and Noir descend into the vault underneath Castle Eschenbach. All the traps should be disabled in this ancient maze, right?

The Heroes Return home and reminisce.

The three heroes return to Flonyard but Shinku and Nanami's summoning is disrupted by a lighting bolt, leaving them stranded in a forest. While their friends search for the duo, they meet a girl named Sharu who offers them aid.

Cinque and Nanami help Sharu protect the forest against hordes of rogue beasts, but after reuniting with their friends, a bigger threat appears.

The armies of Biscotti, Gallete and Pastillage join forces to vanquish a powerful demon that threatens the forest. To help Sharu seal the demon, Cinque, Nanami and Rebecca bring their powers to the limit.

With the crisis averted, the heroes return to their respective kingdoms, but when Nanami and the Genoise Trio pay a visit to Pastillage, they get into a slimy mess when some dangerous creatures break free at the castle.

Cinque and Rebecca joins a scientific expedition that turns into a dangerous adventure when a cursed creature threatens the local Fairies.

The time has come for Leonmitchelle's annual challenge in which whoever defeats the princess earns the right to marry her, but this time, a new and powerful contestant who is an old friend of hers, appears as well.

After almost defeating Leonmitchelle in the challenge, Prince Leaf from the Kingdom of Halver is showed around Galette, Biscotti and Pastillage by the locals, and after attending one of Milhiore's concerts, they gather around Adel, who is about to tell them old stories of the past.

Adel and Valério tell Couvert and her friends their exploits to clear the land of demons along with Brioche, Isuca and Valério's long lost sister, Princess Clarifier, the one who summoned Adel to Flonyard and became her closest friend.

Upon learning that something is amiss with the Sky Priestess, Sharu seeks for the Heroes' aid and departs with them to the insides of the Star Whale, a massive flying deity where she resides.

Upon meeting the Sky Priestess, Cinque's party learns that the Star Whale is infested of demons, and the only way to cleanse it is by the voice of a talented singer. With Aria, the Sky People's songstress unable to sing, Cinque and Rebecca return to the surface seeking Milhiore's aid, but a strange enemy appears, intending to claim Aria for himself.

Once returning with reinforcements, Shinku joins forces with Gaul against Verde to rescue Aria, while Milhiore uses her song to heal the Sky Whale.

Once the Sky Whale is restored, Shinku and his friends return to the surface. Sometime later, the heroes are once again sent back to Earth, promising to return to Flonyard in the near future.
