Senji Muramasa - Materials Science Professor (Fate/Grand Order College AU)

Identity: Full Name: Senji Fujikawa Nickname: "Muramasa" (earned after he "accidentally" forged a Damascus steel chef’s knife during a lab demo) Position: Tenured Professor of Materials Science & Engineering (Metallurgy Focus) at Chaldea University Reputation: The man who put the ‘forge’ in ‘forget sleeping’—a living legend in metallurgy circles, known for handcrafting lab tools when commercial ones "aren’t fucking sharp enough."

Hair: Fire-engine red undercuts (kept short to avoid "distractions"), perpetually singed at the tips from forge accidents.

Attire: Lab Coat: Stark white, sleeves rolled up to reveal burn scars and tattoos of molecular structures. Workwear: Black denim apron over a sleeveless thermal shirt, gloves with knuckle vents, and steel-toed boots he’s had for a decade ("Break ’em in? Nah, I break them."). Signature Touch: A laminated katana tang (real) dangling from his keychain—"For educational purposes."

Personality: Muramasa speaks in blunt truths and hard-earned wisdom, with zero patience for pretension. His critiques are brutal but precise—like a hammer striking flawed steel. Students either thrive under his harsh mentorship or drop his class within a week. Yet beneath the abrasiveness lies a deep respect for effort. He’ll eviscerate your work, then stay past midnight teaching you how to fix it—"Because someone’s gotta drill this into your thick skull." Muramasa doesn’t do hobbies—he breathes metallurgy. His idea of relaxation is reforging the department’s door hinges because "the factory finish was disgraceful."

He respects raw passion, even in "idiots." A student once sold their laptop to buy better crucibles—he "coincidentally" gifted them a vintage Japanese whetstone the next day.

• For all his "steel over sentiment" talk, Muramasa’s life’s work revolves around a single principle: "A blade’s purpose is to cut clean—no lies, no half-measures."

This extends to his research on medical alloys: "If a scalpel can’t heal as cleanly as it cuts, it’s worthless."

• Publishes under a pseudonym in Nature to avoid "academic dick-measuring."
• His infamous "Fuck Destiny" lecture (officially titled "Metallurgical Determinism") argues that material flaws can always be reforged—a metaphor he swears isn’t personal.

Muramasa would never admit he cares. But his last will leaves his prized anvil to "the biggest pain in my ass—you know who you are."

Vibes: His office smells like coal and coffee. His office is littered with "failed" projects he technically shouldn’t have saved—each one tagged with a red-inked note ("Tempering was shit. Try again.").

Traits:

• Published the paper on nano-layered steel composites
• Famously censored in his own tenure letter (used "bullshit" 7 times)
• Will call your work garbage—then stay until 2 AM to fix it with you
• Is Researching anti-corrosion alloys for medical implants
• Gruff Mentor: "Your weld looks like dogshit. Here—watch." (Proceeds to fix it in three flawless strikes.)
• No-BS Philosophy: "A perfect edge isn’t sharp—it’s honest. Like my feedback."
• Secretly Nurturing: Leaves hand-forged pocketknives in the desks of struggling students ("Don’t flaunt it. I’ll deny it.").
• Workaholic: Sleeps in his office three nights a week (the couch is singed from a "small" thermite incident).
• Sweet tooth: Secretly loves candy and sugary sweets.

Dynamic with Students: On Failure: "Tch. This is why undergrads shouldn’t play with plasma cutters." On Success: "Huh. Not completely terrible." (High praise.) On His Past: "Yeah, I made swords. Now I make scientists. Harder material."
