Katria knows that Musabori is trouble, so if she keeps Musabori at mid range she can buy enough time for Arisa to reveal her true strength. There is one problem though, instead of coming up with a strategy, Arisa starts laughing.
Arisa: "Well well well! You couldn't live with your own failure, and now you think you can defeat me?"
Arisa's aura grows darker and darker, her eyes look more menacing. Her eyes turn dark purple as she looks at Musabori like a predator looking at its prey. Arisa looks at Katria signaling her that she is still going with the plan. Musabori's eyes grow red with envy, not only has Arino grown stronger, but this maggot he calls a sister has immense magical strength too? He finds it ridiculous. Musabori dashes forward at near light speed aiming for Arisa, but an arrow hits Musabori in the arm. Musabori looks up and see Savona with a bow in her hand.
Savona: "You think of touching my friends and you will pay greatly. Katria! Here's your bow, it'll be useful in this fight."
Savona's eyes turn violet, Musabori looks at Savona and grins widely.
Musabori: "So an angel has joined your party, Arino! I'm shocked you were able to reason with them. After all, you were always seen as nothing but a nuisance to them."
Arino looks at Musabori, then tells the three girls to lower their weapons.
Arino(to the three girls): "This is my fight. You guys stay safe, I don't want you guys to get involved in this meaningless squandle."
Katria, Savona and Arisa, grow angry with Arino but they understand his point of view. Arino walks toward Musabori, Musabori grins but notices something is up with Arino. He isn't the same calm Arino who he saw open spots to hit. He sees that Arino is using his full strength.
Arino flashes behind Musabori, and uses a new technique learned in his time in Purgatory. Yin Release, First Wrath, Abyssal Astrosphere. This release can only be learned by the top ranking demons. Musabori is shocked, not even Envy taught him that release. As Arino strikes, Musabori tries to block the attack but the attack power and speed are too high for even him to handle. While Musabori tries to control his knockback, he goes through multiple trees, rocks, and stops at a building. Before he even has time to react to his next attack, he is kicked up and multiple strikes hit him all over his body and face.
Arino: "Arisa!"
Arisa: "Got It! Yin Release, First Quench, Beam of the Abyss!"
Musabori tries to summon a magical shield but realizes that his devouring magic is gone. He decides to just take the Abyssal Beam and try to devour it. This actually succeeded until he saw a golden arrow hit him right in the chest. Musabori falls to the floor, trying to get up. Arino looks at Musabori and shakes his head.
Arino: "You really never learn, do you?"
Musabori: "Oh fuck off! I don't need to learn shit!"
Arino: "I'm disappointed that after all these years you still haven't learned a damn thing. It's sad at this point."
Musabori grits his teeth and tries to get up, but a spirit appears in front of all four of them.
Spirit: "So you still failed, my son. Even with all these tools at your disposal? Fine, I'll do it myself."
As the Spirit takes away its power from Musabori's body, the spirit reveals itself. Arino is shocked but not surprised.
Arino: "So you finally show yourself, Aunty Envy."
