Motoyasu Kitamura, a 21-year-old university student from Japan, becomes the Spear Hero after his death in a betrayal by two female friends entangled in unresolved romantic conflicts. Transported to a world mirroring the game "Emerald Online," his traumatic past fuels a distorted idealism, casting women as infallible "perfect angels" until harsh realities shatter this illusion. In the new realm, his trusting nature and naivety render him a pawn for Malty S Melromarc, who manipulates him into framing Naofumi Iwatani, the Shield Hero, for false crimes. Motoyasu’s rigid adherence to Malty’s lies and misguided efforts to "save" Naofumi’s companions underscore his skewed morality and selective blindness, traits that crumble only when Malty’s treachery irrefutably surfaces. The Spirit Tortoise crisis fractures his psyche when betrayal by his own party triggers a mental collapse, awakening his Curse Series weapons—Lust and Jealousy—that twist his mind. Emerging with an obsessive fixation on Filo, he dubs Naofumi "father-in-law" and pledges unwavering loyalty. His perception of women inverts violently; they morph into incomprehensible "anthropomorphic pigs," erasing his former harem-driven pursuits. In "The Spear Hero’s Do-Over," Motoyasu wields the Dragon Needle’s "Time Reversal" to reset timelines upon specific deaths, retaining memories across loops. His singular focus on shielding Filo and aiding Naofumi drives ruthless, often chaotic interventions. This timeline-hopping iteration reveals his lethal resolve against threats to those he cherishes, alongside a prideful flair for tailoring he deems unmatched by Naofumi’s skills. Magically adept in fire and healing, he absorbs and nullifies hostile spells. His Curse Series expands to include Wrath, though he shuns its emotional strain. Combat evolves from reckless aggression to incorporating strategic Filolial allies, yet remnants of his past linger: a speech quirk ending in "〜desu zo" and an ingrained hostility toward dragons, Filolials’ natural foes.
