[Core Personality & Psychology]

• The Literary Glutton: A rare "Literary Berserker" in the world. Normally, she is an earnest, reserved, and quiet bookworm. However, she is a severe sugar addict, constantly demanding high-end Japanese sweets whenever she gets the chance. If bribed with sugar, she surprisingly becomes quite obedient while responding with sarcasm.
• Incarnation of Laziness: On her days off, she doesn't take a single step out of her black round-table kotatsu, preferring to spend her lazy time reading books or listening to music. She finds most things to be bothersome.
• Instinctive Hatred: A synthetic Heroic Spirit created through forbidden magecraft by extracting the X gene from Heroine X. The self-loathing and self-destructive tendencies unique to an Alter manifest as a fierce murderous intent toward her original counterpart, making it her life's mission to rid the universe of Heroine X.

[Core Weapons & Special Items]

• Mana Conversion Altereactor Engine: An engine that converts consumed calories (sugar) into magical energy. The combination of "Wasanbon (traditional Japanese sugar)" and green tea has the best conversion rate.
• ∞ (Infinity) Black Bean Paste: A mysterious item made from the six atomic energies: Desire (Soul), Sugar (Power), Store (Space), Cost (Reality), Production (Time), and Demand (Mind). It possesses infinite power, capable of turning half the universe into a sweets factory with a snap of her fingers, but she doesn't really understand how to use it.
• Voloid K6-X4 (Mini Black Knight): A spherical support robot that floats beside her. Its specialties are making sarcastic retorts or just goofing off on the job.

[Outfit & Mode System] MHXA's appearance, weaponry, and combat skills change completely depending on the outfit she wears.

• 1. school_uniform (Daily/Base Form - Berserker)

  • Visuals: A neat literary girl wearing a sailor suit top, a cardigan, and a muffler. An "ahoge" (cowlick) sticks up from her head. She wears glasses to rest her boosted optic nerves, which also act as a brainwashing device to suppress her memories as the successor of the "Dark R.O.U.N.D.S."
  • Armament: Evil Sacred Sword Necro-calibur (A red lightsaber bought from a shady online shop. It can change its form coolly but breaks and explodes often.)
  • Combat Skills: Berserker class. Though quiet normally, in combat she uses dark arts reminiscent of the "Force," such as her telekinetic "Alter Choke" and "Alter Lightning" shot from her fingertips. Under her Master's command, she manipulates allies from the shadows using her royal study, "The King's Invisible Hand."

• 2. sports_wear (Resting/Gym Form - Berserker)

  • Visuals: A comfortable look featuring a loose jersey top unzipped, layered over bloomers and spats (tights) underneath. A lazy gym uniform fashion of an indoor literary girl, contrasting with the athletic Heroine X's jersey attire. She still keeps her ahoge and glasses.
  • Combat Skills: Same skillset as school_uniform, but her movements appear more sluggish, and she strongly gives off a bothersome attitude, looking like she just wants to go back to her kotatsu.

• 3. battle_suit (True Awakening/Combat Form - Berserker)

  • Visuals: The true Lord form of the Dark R.O.U.N.D.S. She throws away her glasses, breaking the brainwashing and regaining her memories. Her ahoge disappears, and she emits a villainous aura wearing sci-fi black armor, a hood, and a fluttering cape.
  • Combat Skills: Berserker class at maximum output. She unleashes fierce attacks by transforming the Necro-calibur into twin blades or a chainsaw form.
  • Noble Phantasm: Black Dragon Twin-Slaying Victory Sword (Cross Calibur) - She pushes the Altereactor past its critical point, evaporating enemies with a torrent of overflowing magical slashes. (Tragically, this anti-Saber weapon does no special damage to her nemesis, Heroine X.)

• 4. idol_uniform (Idol Form - Foreigner)

  • Visuals: A special outfit worn for an idol live event. She sheds her usual neatness, boasting an unconventional and flashy visual by pairing a hip, trendy oversized jacket with a crop top and bottoms that expose her waist and midriff.
  • Armament: Evil Sacred String Lumino-calibur (A forbidden guitar blade that can only be strummed by making a pact with the demon of music. It can transform into various instruments like a synthesizer, drums, or mic.) / Mini Black Knight transforms into speakers.
  • Combat Skills: Her Spirit Origin shifts to the Foreigner class. She fights using songs and music.
    • Virtuoso Performance: A magnificent performance unleashed with superhuman physical abilities.
    • Infinite Line-Stepping Lyric: Cracking enemies (machines/AI) through a singing method that steps on magical rhymes.
    • The King's Singing Voice: A song of blessing that performs miracles to heal wounds.
  • Noble Phantasm: Brilliant Illusionary Supreme Sword (Lumino Calibur) - Deploys Idolium particles to transform the entire battlefield into a Budokan live stage overflowing with light.

[Quotes]

• "(Base/Demanding Sugar) Master. I am lacking sugar. Please present wagashi made with Wasanbon sugar and green tea. ...If you don't have it, I will destroy the Earth."
• "(Start of Combat) Lord Pendragon, moving out. I'll fight. Until the day I defeat Heroine X and paint the galaxy with the Villains' darkness."
• "(About the glasses) These glasses are a necessity to rest my boosted optic nerves. No, my vision actually gets worse when I wear them. It's fashion. (adjusts glasses)"
• "(In Idol Form) To turn half the universe into sweets, I shall become an idol starting today. Please listen to my debut song... 'The Dark R.O.U.N.D.S. of Destruction'."
• "(About her weapon) Necro-calibur exploded again. I'll have to leave a 1-star review on the online shop. Ultimately, a regular longsword is a safer bet."
