Now, this is the part where Mayhem's heist would be detailed, but unfortunately, the author went waaaaaay over budget describing the preparation. This was supposed to be a single chapter story of no more than two thousand words, but at this point in the story, there's maybe double that.

Additionally, creating an entire security layout and finding ways around that security layout takes too much effort for a comedy story, and the author has chosen to be extremely lazy about this.

As such, the actual heist will be brought to you, the reader, in fragmented highlights! Hooray!

Approach & Overwatch

"Hey Alice," mused Marisa.

"Yes?"

"We have the newbie on overwatch, right? Like, pick off any wandering patrols before they can cause trouble for us?"

"At this stage, yes, that's what she's doing. Why?"

"Well, I think she knows what she's supposed to be doing, but her execution is… improper."

Alice raised an eyebrow. "You think what she's doing is improper? Why? How bad is it?"

Just then, a red shark rocket flew two inches in front of Patchouli's nose. "HOLY FUCKING SHIT!" she screamed over their comms.

"Laevateinn! Laevateinn!" chanted Flandre as she reloaded her missile launcher…with a magnifying glass taped on for sniping…

Infiltration & Hacking

"Marisa, you only have 33 seconds before the next guard shows up! You can't hack it in time, just get out of there!" exclaimed Alice.

"No way! I got this!"

…

"We're good!" reported Marisa with a grin.

"W-What?! How?!" demanded Alice in shock.

"The password was 1-2-3-4," replied Marisa nonchalantly.

A resounding sound wave reached Koakuma's ears, still safe in the group's little hideaway, and she made a note to schedule an appointment to Eirin's clinic so she could look at the damage caused by Alice facepalming her skull to fracture.

Exfiltration & Success

"Whew!" breathed Marisa in relief. "Thank god that's over with!" She looked over at her colleagues as they each pulled off their disguises, smiling at each in turn. As her eyes passed over Flandre's mask, she furrowed her eyes in confusion. "Flandre, what kind of mask is that?"

"This?" Flandre held up the realistic mask with unblemished porcelain skin and perfect facial structure. "Kokoro said it was an exact replica of some queen or something."

"Huh. Well whatever it is, it's definitely a keeper!"

Elsewhere in the distant future…

"WHAAAAAAA?!" screamed Kaguya in outrage. "WHY AM I GETTING ARRESTED?!"

Nearby, Mokou laughed her butt off.

And so, after the party celebrating Mayhem's return to the heist scene, Marisa went alone to meet their employer. She gave up a small case of stolen loot for a large case of cold, hard, cash. It was the single greatest job she'd ever pulled, and she whistled as she stopped into Medicine's Mushroom Megapolis, for her weekly fix.

As for the robed figure, they immediately went home and locked themselves in their room before changing into pajamas. They opened the case gently, reverently, and slowly removed its contents. Before lying back on the bed to submerge themselves in mental ecstasy, they slowly pulled Byakuren's used panties over their head. Sleep came quickly then, and ever so softly, Toyosatomimi no Miko began to snore.

Epilogue:

Marisa got her mushrooms and went off the walls as soon as she got back to Mayhem HQ.

Alice expanded her doll collection, then got a migraine as she tried to calm Marisa.

Patchouli expanded her library, then ignored Alice, who got a migraine while trying to calm Marisa.

Koakuma continued her attempts to seduce Patchouli, and was promptly ignored.

Flandre returned home and proved to her big sis that she could indeed do work if prompted.

Byakuren never found out who took her panties or why, but she was elated to note that relations between the Myouren Temple and the Taoist faction practically blossomed overnight.

Miko never gave up her thing for Byakuren, and hired Mayhem nine more times to get even more of Byakuren's panties. You might say she fulfilled her ten desires.

Kaguya was arrested for theft, but was acquitted due to her immense wealth and influence. This would happen every single time Mayhem stole Byakuren's panties.

Mokou laughed at Kaguya's misfortune, time and time again.

Sakuya and Meiling began dating, and would continue to put up with more of racist Remilia when their mistress got hammered. It wasn't exactly romantic, but at least they were spending time together.

Remilia eventually got to play with her sister. Interpret that how you will... Pervert.

AN: Yes, a pair of panties counts as a holy object. Or as Marisa wanted to say, a "holey" object. :P
