Who is the Lamb (and Who is the Knife)? by MapleWood_Snow

Summary
SCP Foundation AU:
In a world where Rumi is an SCP anomaly - rather than a half-demon K-Pop Idol and Hunter, Zoey is a major researcher of anomalies at the facility, and Mira is one of the guards who enforces the Foundation’s protective measures by keeping the SCPs in line — the trio go through challenges, trauma, and hurt before eventually uniting themselves in a precarious-yet-nurturing dynamic, positively impacting their collective mental health in these awful conditions and the complexities of working/living at the Foundation.
Yet, as a group, they must go through harrowing experiences and tests of trust before coming together, and this is their story of how the unconventional polycule came to be.
(Aka: my take on a Polytrix slowburn SCP Foundation au with extra angst sprinkled on top. Any comments/kudos would be GREATLY appreciated and constructive criticism is welcomed <3)
A/N: Rated Mature for violence and gore. Please don’t ignore the tags, they will become relevant in later chapters if they are not already relevant in the current ones posted.

Summary
Как странно было то, что главная головная боль была для Арлекино единственным утешением в этом морском аду. Как быстро эта пугливая русалка расположила к себе холодного директора... Прошло всего два месяца со дня их первого разговора, но Арлекино уже не могла представить себе жизни без огромного глубоководного монстра. Как смешно это выглядит со стороны.
Маленькая история о том, как русалка влюбилась в директора научного комплекса.

Summary
At first it’s hard to say what plagues Hiromi the most: the tickle of the plaster dust in his nose and throat or the blaring klaxon of the system alarm which threatens to explode his eardrums; but as the room—his office—blurs and comes back into focus again, he reaches a conclusion:
At least he can turn the damn alarm off. That’s one point in its favor.
“Deafen alarm!” Hiromi shouts.
Another bit of plaster falls from the ceiling and Hiromi coughs from the ensuing cloud of dust. He rolls onto his side, putting himself into the Recovery Position in accordance with the Foundation Emergency Handbook: Section 2, Paragraph 4(a), and begins to Assess.
[OR: Higuruma Hiromi is the Site Director of Nihon Containment and Preservation Site 7. Unfortunately for him, it's about to be a very, very bad day.]

Summary
"... What?" Wifies asked, confused
"You know," he walked closer, setting down his tools, "try to figure out my favorite color, or hobbies. Could be fun, if you don't wanna be bored."
Wifies smiled, now looking up at Parrot. "And I assume you read my file and don't want me to get bored?" He had a humorous lilt in his voice, teasing Parrot for his suggestion.
"Well. Yeah." Parrot opened the box, fingers methodically finding a sterile glove pack. "Wouldn't anyone?"
OR /////
Parrot works at the SCP Foundation but doesn't get to meet any of the fun and cool SCPs- well, until Wato asks him to fix a higher clearance SCP: Wifies.
