Blueman, formally named Blue Manjaro, is a member of the cat-featured Nekomatango race and operates as the primary thief in his adventuring party. His specialties include lock-picking, disarming traps, and breaching secured doors or chests. Despite his short stature and fluffy, deceptively innocent cat-like appearance, his demeanor contrasts sharply—marked by a tough, pragmatic, and sarcastic temperament. He consistently serves as the group's strategist and advisor, cautioning Mocha against rash decisions and evaluating risks during missions. While intensely driven by money and treasure, he demonstrates loyalty and honor, engaging in efforts to prevent catastrophes even without assured payment. Blueman communicates verbally and collaborates actively with companions in combat and exploration. As a core member of the traditional adventurer trio alongside Mocha and Kiliman, his thievery and trap-management skills are indispensable for navigating dungeons and achieving objectives.
