Summary
Sitting by the table at the Maple Tree guild HQ, Maple plays with Syrup using her newly acquired tentacles as Sally sits beside her and watches. Iz who also sat at the table comments how Syrup fond and Oboro were of Maple's tentacles. Talking about preparations for the upcoming Fifth Event, Kanade comments how he hopes to acquire a versatile pet that compliments his support style. Chrome chimes in and claims that a pet with a healing power would best suit him and Iz believes one that specializes in production work would be best for her. With that, Iz, Chrome, and Kanade all decide to spend the day searching for companions of their own

Kanade walks around Level Six seeing if there's anything hints or clues around the area that'd help his search for a companion. He'd also walk past the members of the Holy Swords purchasing potions. One of the members mentioned their purchase was for Dred and all that remained was for what Drag wanted. Immediately after this, Kanade spots a new NPC and tails him to a lone house in the woods. Upon inspecting the house, Kanade examines the bookcase, but leaves "unhappy" that he found nothing out of the ordinary. However, moments after he left, Kanade reenters the house and finds that the books on the bookshelf have been rearranged and learns that one of them was a Mirror Slime.

After accepting the quest attached to the monster, Kanade follows it to a crystal cave where his reflection is casts on every crystal there. Through careful examination of every crystal there, Kanade manages to locate the Mirror Slime that takes his shape, and fights it to submission. Learning that its taming conditions were to show it fifty skills or spells, Kanade does this and tames it, thereby naming it Sou.

Meanwhile, Iz looks at the Level Six quest board searching for a quest related to a monster quest that'd help her find a production focused companion. In her search, Iz finds a quest a newly discovered Spirit-Type monster and after accepting it, she visits the quest giver, a dwarven blacksmith. As the blacksmith steps away, a new quest pops up for Iz that asks she create and max out three craftable items with specified abilities. The blacksmith then hands Iz a few papers of the items and claims that spirits are fickle beings and she'll need to prove herself to them if they wants to their aid. With that in mind, Iz accepts the quest.

Afterward, Iz laments on how the requested items she has to make are crafted with high-level materials. She then runs into Maple and Mii who were about to go hunt some monsters. However, after hearing about Iz's quest, Mii was more than happy to agree to help Iz with her quest. In Mii's opinion, it'd not ony be advantageous for her fighting strong monsters, but also analyzing the a rival guild's capabilities.

Their first destination was a volcano which they all reach there via Mii's companion Ignis, a phoenix themed companion. Because Mii was familiar with the place, Iz and Maple follow her through the area. As Iz first collected some plants and ores, Mii and Maple fight against the monsters that came there way. Once that was over with, Iz uses a couple of potions to heal them and they continue onward and face off against the Lava Dragon Boss. After it was defeated, Iz collects its material drop and the group leave the volcano while heading off to the other areas where the remaining quest items are located.

Elsewhere, Chrome on a quest of his own, carefully tries not to fall off a cliff where the ocean current thrashed below. Restless after searching several different places all of which were dead ends, Chrome soon spots a cavern by the end of the walkway. Walking through the dark, narrow, and bone littered pathway, Chrome defeats some zombie monsters and finds a new scythe wielding monster accompanied by some more zombies. Making it past the monsters, Chrome reaches the end of the tunnel where he finds a ghost ship and faces off against a horde of monsters. Boarding the ship, Chrome fights against the Skeletal Pirate boss and defeats it. After which, Chrome finds a treasure chest and inside of it he finds the ring to the armor monster companion, Necro.

Returning to Iz's side, she completes her quest for the spirit companion where she gains Fay.

Later at the Maple Tree HQ, Iz, Kanade, and Chrome all show off their newest companions to their guildmates.
