As Muichiro carried Kotetsu on his shoulder, he asked if they were heading in the right direction, to which Kotetsu answered yes. Muichiro soon spotted a fish demon up ahead, attempting to climb up a tree to reach Kozo. Muichiro rushed, slashing the demon's vase, killing it and saving the swordsmith. Kotetsu and Kozo both expressed relief at seeing each other safe, while the Hashira asked if he is the one named Kanamori and asked if his sword is complete. Kozo quickly noticed that the blade Muichiro was using was badly chipped and stated that his own blade is indeed prepared. Kozo added that Tanjiro had previously asked to understand him, which surprised Muichiro, but then Kotetsu cut off the discussion, reminding them that Hotaru was still in danger!.Which Kozo acknowledged, leading the way to his work shed.

As they head into the forest, Kozo spotted a blade that the Mist Hashira can use, asking that he use it to protect the chef. Muichiro suddenly pulled the swordsmith back and warned him that something is coming!. A porcelain vase emerged, and with the Transparent world, Muichiro immediately knew that a demon was inside, Muichiro as well as all the other Hashira had all awakened their Demon Slayer Marks and the transparent world during their previous training with Tanjiro.
"I see you, you can't hide from me demon!." shouted Muichiro.
"Oh you're a Hashira, it's no wonder that you're able to notice me, i Gyokko am impressed, still a child but already a Hashira, you're a rare talent." said Gyokko as he emerged from his vase.

As the swordsmith village was besieged by Gyokko's Blood Demon Art fish demons, the villagers desperately rallied themselves together, and orders were given to protect the Hashira's weapons and the chief. The demons began to attack and kill them, while the swordsmiths struggled to stave them off and survive. When one demon cornered a group behind a house the love Hashira arrived at the nick of time and sliced through its vase saving them. Mitsuri apologized for being late and began to kill all of the demons in rapid succession, much to the smiths amazement. They call for the village chief to be saved and she made her way to rescue him.

At Tecchin Tecchikawhara's residence, an enormous fish demon held the chief in its grasp and began to crush him to death!. His aide attempted to save him but was knocked aside, as he saw that the Demon Slayers that were stationed to protect Tecchin had all been killed. Despite his efforts, the demon proved to big and fast for him to stand a chance. Luckily Mitsuri arrived, the Love Hashira asked the aide not to move due to his internal injuries, he was amazed by Mitsuri's strange wip-like Nichirin sword which was forged by Tecchin himself. The demon roared in anger."Love Breathing First Form, Shivers of first Love." yelled Mitsuri as she sped around the demon's body and eviscerated the monster, killing it instantly. Mitsuri couldn't stand the needless harm done to others. The demon burned up, and chief Tecchin nearly fell when its hands faded away.
"Oh are you ok Chief Tecchin?!." Mitsuri asked desperately as she caught the falling Tecchin.
"No worries, i'm ok now that i'm bring held by a pretty young woman" laughed Tecchin, this caused Mitsuri to playfully chide him. Another injured swordsmith made an attempt at Mitsuri's attention, but Chief Tecchin did not want his moment ruined.
