If 'Happy Ever After' does exist ✔

"Don't you think this is too silly?", Alhaitham asked rhetorically as he put down the book he was reading.

"Hey! You agreed to help when we asked you first. Don't you complain about it now", Paimon stomped her little feet in the air.

"I thought it was supposed to be a small gathering for an important mystery discussion", he crossed his arms firmly.

"It is a mystery!", the twins argued back at the same time.

He shut up with a gulp at the sight of their angry pouts and switched his gaze to the other people in the room, "so, I assume everyone else knows and agrees to this ... 'Satan summoning'?"

"I don't know what this 'Satan' is but it sounds interesting enough based on them. It sounds like a pretty powerful entity. It will be worth it for experiments", Albedo looked up from the floor where he was laying down some items that the twins requested.

"Eh? You want to experiment on Satan?!", Aether flinched at him.

Lisa spoke after sipping on her tea, "relax, Alhaitham. It sounds pretty fun. Not to mention this 'Latin' language they mentioned is a foreign kind that we have never heard before" and slided her green eyes onto the man in front of her, "it will be a great learning experience, isn't it right, Zhongli-xiānshēng?"

Zhongli, who was sitting opposite of her, also put down his teacup, "Indeed, I've never heard of this ritual before. Since the twins said this practice was from another world, it will be quite a remarkable event to witness."

"In the last world we visited, the Earth, they summoned this entity named Satan devil for various reasons. He can fulfill any good or bad deeds with the exchange of your sacrifice value. So, we get curious if he could be summoned here as well. Of course, since it's just because of our curiosity, we won't ask anything expensive. Just harmless stuff", Lumine explained with excitement.

Grinning Childe wrapped his arm around the younger twin, causing the girl to blush slightly, "I don't understand a thing about this Satan but if my comrade is doing, I am doing it too!"

Aether pried the ginger away from his sister, "and I told you multiple times that you aren't invited to our teapot! Who told you about today anyway?"

When Childe only threw back a winning smirk, Aether gasped dramatically at Lumine, "Lumi! Don't tell me you invited this brute?!"

"Jeez, Aether. Keep it down, will you? We have to focus on the ritual", she escaped his question by walking away with the scented candles.

"This ain't over yet!", he shouted after her before helping Albedo with the chalk drawing on the floor. Childe promptly followed Lumine to help her place the candles on designated places.

"Come on, we should cover all doors and windows", Paimon flew by the others with cloth in her hands. The three respectively took some and went to cover all the holes that light could enter. When they returned, there was a ritual being made. A large salt circle surrounded the chalk drawing of an inverted pentagram. Six big scented candles were placed in it while the smaller ones took place in different places of the living room.

"Whoa! It got really dark now. Paimon wouldn't know it is daytime or nighttime", Paimon floated near Aether.

Aether spoke with his hands on hips, "it's supposed to be done during the night time but my sister here got scared of a little darkness."

"It's dark now, isn't it? This is fine", she glared back at him.

"So, what are we doing next?", Albedo asked calmly from Aether's side.
