The surgery kit is one of Devil Hunter's most misunderstood items — new players either never pick up the free quest reward and wonder why hybrid NPCs ignore them, or burn their only kit on experimental contract swaps and stall the Katana Man path for days. Surgery kits enable medical narrative sequences tied to contract extraction and hybrid transformation prep. Without a kit in inventory at the right quest step, story markers simply do not advance. This guide lists every acquisition path, yen costs versus raid RNG, and consumption timing so your first kit lands on hybrid unlock rather than a D-tier devil you planned to replace anyway.
Free Quest Method
Mid-progression HQ missions introduce a medical subplot after you meet several division captains from divisions walkthrough. Follow mission markers to the quest giver — often near HQ medical wing on Headquarters map. Objectives typically combine a devil kill on Floor Zero with a turn-in to the surgeon NPC. Completion mails one surgery kit to inventory automatically. If the quest never appears, verify tutorial completion with Kintoki and First Class Hunter progress from rank up guide.
HQ Vendor Purchase
After quest unlock, HQ vendors sell additional kits for yen. Farm missions from progression guide before buying — prices hurt early budgets competing with weapon crafts on weapons page. Buy one backup kit before starting hybrid transformation in case the ritual consumes your free copy.
Raid Drop Farming
Hotel and School raids occasionally drop kits in reward tables per raids walkthrough. Drop rates are low — treat raids as supplemental, not primary, if the free quest remains incomplete. Party clears speed attempts; Violence Tank stabilizes learning groups.
Black Market Option
Rare stock on Black Market map sometimes includes kits at premium markup. Only purchase when invasion routes are quiet or you travel with escort — losing yen and kit runs to PvP doubles the pain.
