Shinya Kamihara, the Pro Hero Edgeshot, forged a close bond with Tsunagu Hakamada (Best Jeanist) while attending U.A. High School, where they co-founded the "Textile Arts Association" with Hakamada as president. Post-graduation, Kamihara embraced his ninja-themed identity, climbing to Japan’s No. 5 Pro Hero rank. After All Might’s retirement, he advanced to No. 4. He commands the hero team "The Lurkers," recruiting Kamui Woods (No. 7) post-Kamino Incident collaboration and later adding Mt. Lady (No. 23). His costume features traditional ninja elements: a blue mask, red shinobi shozoku, and a red scarf with a white patch. Edgeshot wields the Quirk "Foldabody," thinning his body to slip through crevices, stretch limbs, or launch piercing strikes faster than sound. Techniques include "Thousand Sheet Pierce" (blocking blood flow), "Spiral Spear Hand," "Fishhook Snag," "Substitution Jutsu" (log evasion), and "Pulp-Thread Throttle." His ultimate move, "Zenith," thins his body to suture internal injuries at the cost of his lifespan. In *Vigilantes*, Edgeshot aided Captain Celebrity’s Tokyo Sky Egg event, neutralizing Bombers with Best Jeanist. Later, during the Naruhata Lockdown, he apprehended vigilante Koichi Haimawari and fought Number 6’s forces, using Substitution Jutsu to shield civilians. During the Hideout Raid, he joined Bakugo’s rescue, incapacitating Kurogiri with Thousand Sheet Pierce before aiding Endeavor against All For One. In the Paranormal Liberation War, he defeated Re-Destro solo, sustaining moderate injuries. In the Final War against Tomura Shigaraki, Edgeshot deployed "Zenith" to save Bakugo from fatal heart damage, transforming into thread to stitch the organ. This sacrifice reduced him to a miniature form, depleting his body mass. Eight years later, advanced overseas treatments facilitated his recovery; he remains small with a regrown head and rudimentary arms, slated to resume hero duties. Edgeshot maintains a shinobi’s calm, analytical approach, prioritizing strategy in crises. His selflessness drove the Bakugo rescue despite no prior closeness. Professional evaluations grant him maximum scores in Speed and Ninja skills.
