Arino explains his backstory to Arisa. The more he talks about his past, the more angry Arisa becomes. Arisa couldn't believe the clan that raised her so well can do such a thing like banishing her brother at such a young age. When Arino kept talking about his experience outside the clan not being much better, she just sat in disbelief.
Arisa: "If I'm being honest, before I got chosen for this Guild Master job, life was a tremendous pain in the ass. Everyone just turned the other cheek to me because they kept relating me to the Son Of Greed. I never met our father, but am I really the Daughter of Greed?"
Mammon: "It seems you two have finally reunited! I'm pleased that this happened."
Arino: "Mammon? You were listening?"
Mammon: "Why wouldn't I watch my two children unite for the first time?! I may be a Sin, but I'm not that terrible."
Arisa: "So... we are the children of Greed?"
Mammon: "Yes you two are. They could only save one of you, and when it came down to choosing, Arino didn't want you to go with them. So he stepped up and took the stage as the burden that needed to be sent away. Arino, you are a kind soul, no wonder why The Most High chose you!"
Arino(embarrassed): "hehe... I only wanted to be a good sibling y'know."
When Arisa heard that Arino was banished in order to keep her safe, she started to blush heavily. She realized that he did all of this for his little sister.
Arisa: "I want to help you with your task, Brother!"
Arino: "Are you sure? It is a really big task and plus you have this guild to run."
Arisa: "This guild can get a new leader easily, I already recommended someone for the job."
Mammon(tearing up): "It's so lively seeing my two kids again for the first time in a long time! It's refreshing that I can be a father figure without the bad rep of the Akumo Clan."
As Arino and Arisa finish up their rendezvous Katria and Savona arrive. As soon as Savona sees Arino with the GuildMaster, she instantly gets jealous. The same went for Arisa, when she saw Savona she instantly started hugging Arino tighter. Arino, confused, looks to Katria for assistance. Katria just chuckled and shrugged.
Mammon: "Now that all of you all are here, I have to update you on the state of the Tenshi household."
Arino: "What happened with those fuckers now? Are they still wreaking havoc on the people?"
Mammon: "No, it isn't Katria's father this time... It is Satan."
Arisa(facepalming): "I knew this was going to happen. If Ronin weren't so petty he would've foreseen all this. This is what happens when you can't control your magic. The mentally unstable make the easiest test subjects."
Arino: "I agree. I see why you left, Katria."
In the Tenshi household, Satan laughs as the Tenshi household's lower angels try desperately to defeat the demonic powerhouse. Ronin limps away like a coward; he knows he has no other choice if he wants to live. Ronin wants to go to Katria but he knows he can't go to them. If katria sees him in the way he is now, he'll be seen as nothing but a pathetic waste of a Tenshi to her. Even then he knows that even if her daughter doesn't accept him, he has to at least apologize. He has to put his ego aside for once just for a chance at keeping his sanity. He has to look to one he gave up on when he needs her the most.
Ronin: "I'm so pathetic."
I decided to appear in front of Ronin; disappointed in how pathetic he has turned out to be. Ronin looks at me and just lowers his head in utter shame. He can't even plead with The Most High, he just has to accept what's coming to him.
The Most High: "Have you learned your lesson, Ronin Tenshi?"
Ronin: "Of course I have, I was riddled with hatred and envy to the point that I forgot what it meant to be a true Tenshi leader."
The Most High: "I can give you another opportunity but there will be one condition."
Ronin: "What is this one condition?"
The Most High: "You and Satan are so alike, you know? Like Yin and Yang. I want you to help Satan. Your daughter would probably kill you if she saw how pathetic you are now."
Ronin: "Yeah that is very much true. So why must I work with Satan?"
The Most High: "It makes things interesting! I can't have everyone be against Satan that's pretty dumb. So I will have you working with Satan directly, only if you want to though. I'm not the type to force things onto you, especially since you aren't a part of The Reborn."
Ronin: "I'll do it!"
I smile as Ronin gets teleported back to the castle. He knows that Satan at least has to have hope in defeating Satan. The Anomaly needs to stay unstable for Satan's power to activate. I do want a new Demon King though, I got just the person in mind! This'll spice up the journey more!
