Upon arrival at the mansion Rem was unsurprised, yet quite annoyed, that Meiling was asleep on the job. He flew over the gate after undoing the magical barrier that keeps most people (mostly book thieves) out. He put Patchouli in her bed and went to put Flandre to sleep. He snapped his fingers upon exiting Flandre's room and was greeted by a maid that appeared before him. He had seen her coming as her manipulation over space was nowhere near as powerful as his manipulation over time but he never brought it up. "Meiling's doing it again Sakuya. Please take care of her." Rem said as he floated back to Viole's unknown area, the bedroom.
"I'll go now. How was Lady Flandre's time?" she replied without surprise at the gatekeepers slacking.
"I think she had fun, considering we played danmaku." Rem replied as he opened the door to Viole and walked into the massive library.
"And nothing happened to make Ojou-sama angry?" she asked with a hint of fear.
"Nothing I can't persuade Remilia to overlook." He replied as they drew near the small door at the back of the library. He stifled a yawn and bid the maid goodnight as she disappeared to take care of the gatekeeper. He retreated into the bedroom and heard a sharp yelp and yelling but ignored what they were saying as it quickly turned to moaning. He slipped into bed with the sleeping magician and fell asleep with the sounds of Meiling and Sakuya in the front and the light breathing of Patchouli in his ear and his arms around her torso.
Rem awoke when a sharp object glanced his face and the screams of the maid and mage were heard close by. The door to the bedroom had been blown apart and several knives were thrown in seemingly random directions that had barely missed him. The scent of smoke and blood was normal in the house and he ignored it as he got dressed and went into the library to find Patchouli, Sakuya, Remilia, and Meiling arguing about something. He was used to little fights like this and kissed Patchouli as he passed by. He proceeded to scold Sakuya and Meiling, then went out the door to the main building. Once there, he went outside without an umbrella and took a quick stroll before he saw a small fairy poking a frog before she froze it. The fairy noticed him and pulled a spellcard from her skirt pocket. She activated it soundlessly even though her lips moved and started firing danmaku that missed Rem no matter where he moved. He took out a spellcard with a symbol and a picture of a fire and said "Alchemic Sign – Flame Alchemy ~ Salamandra" and snapped his fingers. The fairy was lit on fire instantly and dived into the lake as Rem went into the mansion. When he returned Sakuya was cleaning the mess from earlier. "Where's Remi? I need to talk to her about some issues here." He said.
"She's in her room having tea. She's still mad about how late Lady Flandre got home last night." She replied before checking her pocket watch.
"So that's why the door was missing. I'll take the blame for this one. Both Flan and Patchy feel asleep before we left so it's my fault for not getting back sooner. You and Meiling got involved in the fight though. How'd that happen?"
"Ojou-sama asked me this morning what time Lady Flandre got home and Meiling and I happened to be err…" she paused for a moment to come up with an excuse "somewhat indecent when she came so Meiling got drug along when I was forced to help apprehend Lady Patchouli."
"I'll take care of it. And you may want to be a bit quieter when you have fun with Meiling. I could hear you all night." He said with a smirk as he jumped up and landed with ease on the upper floor. He walked down the hallway before Sakuya could throw her knives and arrived at Remilia's door before long.
