Pros & Cons for Gen Narumi (Japan's Strongest Combatant)
Recommended weapons, Uniparts, and squad comps for Gen Narumi will be added soon. Please stay tuned for updates!
Versatile Dual-Element Attacker
Narumi wields both Slash and Shot elements, making him a valuable dual-element wielder. While both are physical types, his versatility shines in battles where enemies have high Physical RES and this trait alone gives him an edge over characters wielding only a single-element.
Strong in Multi-Enemy Encounters
Narumi's Combat Skill and Ultimate both target adjacent enemies. He has a wide attack range, and excels in mob battles where multiple small-sized Kaiju are lined up.
Performance Changes Depending on the Ultimate Gauge Level
Narumi’s Passive Skill shifts depending on his Ultimate Gauge level. Below 50%, he gains a Speed buff which helps him act faster and charge his Ultimate gauge more quickly. Once the gauge hits 50% or higher, he receives a DMG Dealt buff when he uses his Combat Skill. This mechanic makes Narumi an easy-to-play character who can become increasingly more powerful as his Ultimate builds up.
Core Exposed Damage Specialist
Narumi’s Combat Skill inflicts a Core Exposed status on Kaijus and advances his action order, letting him strike again sooner. Against core exposed enemies, he gains a DMG Dealt buff—making him a high-damage specialist who excels at creating and punishing vulnerabilities.

Introduction
Gen Narumi is the Captain of the Japan Defense Force's First Division. Despite his title, he approaches work with a strikingly lackadaisical attitude. His office is a chaotic mess of personal items, and he's a chronic offender when it comes to tardiness and slacking off. Yet despite his carefree demeanor, he remains captain for one undeniable reason: he is Japan's most formidable anti-Kaiju combatant. |
