Echo Gorge arc
On the way to Liones, the trio decide to stop for a meal, which Percival suggests a competition to see who catches the biggest bird prey. Donny is confused with the personality of the supposed "knight of the apocalypse" and then asks him to give him his bow and arrows. Donny fails to capture any prey with the bow, earning Sin's taunts. In that, a scream after a lost arrow leads them to meet a young giant woman. When some fairies appear talking about a boy who got into the Echo Gorge, Donny tells them that it must be Percival. Fairies explain that Echo Gorge used to be beautiful but now it's hell.

Upon entering the Echo Gorge and being attacked by monstrous animals and plants, Donny tells the fairies that it is the work of a boy named Nasiens, although Dolores denies it. After finding Percival in the company of Nasiens, Donny explains the situation to him. After Naseins revives Echo Gorge and its truth is revealed, a monstrous Ordo appears controlled by a strange fairy. Donny shoots several arrows at the fairy, missing all of them, although a different arrow manages to hit it, revealing that the fairy was a puppet controlled by Talisker.

After Percival defeats Talisker, Nasiens decides to join the group. Donny is reluctant for his attitude and for calling Percival his "guinea pig", but Percival agrees to have him join. Saying they need transportation to get to Liones, Nasiens suggests going to Sistana to get it, starting an argument with Donny.

Sistana arc
When the group stops to eat, Donny uses his magic to catch a fish. After enjoying the food that Percival cooks for them and having some roses with Nasiens, they discussing the events that Percival, Donny and Sin went through before meeting Nasiens,Donny berates Sin for not having used his only Incantation Orb to take them to Liones.

Upon reaching Sistana, a mini golem leads them to find a piece of the Coffin of Eternal Darkness buried. Hearing Nasiens and Sin saying that it is an ancient relic, Donny is excited to be able to sell it. A girl suddenly arrive and warns them to leave it and to kill them if they intend to give it to "that man".

Although Donny tries to explain that they happened to find it, Anghalhad pulls out his rapier and attacks him, managing to dodge and knock him down quickly. She then demands that Percival give her the piece and to her surprise, the boy kindly gives it to her. A maid appears telling Anghalhad that she must return for the dance that is about to begin. Anghalhad rushes to return the Coffin's piece to Percival demanding that he hide it and not let anyone see it, especially Ironside. She then leaves with her maid.

At night, the four of them stay at an inn. Nasiens explains to them that the girl is the daughter of the Lord of Sistana and Donny wonders what problem he has with them and the Coffin's piece. They then spy on Ironside's speech to the townspeople, revealing that he owns the other pieces of the Coffin. Sin reveals to them that Ironside plans to kill everyone in town to activate the Coffin magic. Sin suggests that they escape with the missing piece, but Percival sets out to save Anghalhad when she interrupts the speech. Nasiens, Sin, and Donny run to the inn, but discover the maiden stealing the piece, actually being Ironside's familiar in disguise. After meeting with Percival and Anghalhad, Donny reluctantly agrees to help them stop Ironside.

During the fight that breaks out with Ironside, Donny decides to run away upon seeing the power of the Holy Knight. As he runs, Donny sees all the townspeople suffering from Ironside's monsters, leading him to feel like a coward. Donny finally returns to battle by making a dramatic forced entrance. When wondering about Percival, several of his mini golems absorb him as Ironside use his Ragna Claw. However, a revived Percival saves everyone with his magical power, which is revealed to be the power of Hope.

Ironside launches his attacks at him, forcing Percival to fly all over the place to evade them. In that, Donny uses his telekinetic powers to levitate the Coffin away from Ironside, allowing Percival to re-divide it. Donny then captures the Dragon Handle. Ironside claims they haven't stopped him as he just has to kill them and reassemble the Coffin and gather more sacrifices from Britannia. However, another Holy Knight, Mortlach, appears stopping him from continuing the fight and reminds him that whoever destroyed the monsters he summoned must be someone as strong as the Seven Deadly Sins, so in the face of such a threat, it is best for them to retreat.

As everyone twists after the hard battle, Anghalhad reproaches Donny for escaping and tells him that they would all be dead if it were not for Percival. Donny and the rest ask Sin who he called to get rid of the monsters, not believing him when he says they were his "forest friends".

The next day, Carden fires them thanking them for what they did. Donny asks him that he knows Ironside, revealing that he is an old acquaintance of his wife, who like him was a Holy Knight of Camelot. Anghalhad then appears and Percival invites her to join the group.
