Nils Nielsen  

Samurai Boy, ニルス ニールセン

Nils utilizes advanced knowledge and natural talent (possibly from martial arts training) combined with skilled craftsmanship and fine-tuning of his Sengoku Astray to achieve victory through strategic decision making. Despite appearing uninterested in the outcomes or significance of battles, he views them as a means to further his primary objective: advancing his research on Particles.
