Al'Cu Ad Solte, occasionally translated as Al Southwell, operates as a rookie officer within the Tank Police unit, partnering with Leona Ozaki. To preserve her position after her original tank’s destruction, he single-handedly designed and assembled the mini-tank Bonaparte overnight, showcasing his mechanical engineering prowess and aptitude for computer hacking. His technical ingenuity proves vital in field missions, where he continuously repairs and upgrades Bonaparte amid relentless combat.

While colleagues favor aggressive tactics, Al adheres to protocol, employing restrained force and strategic problem-solving. His career shifted from assisting Lieutenant Charles Brenten as a tank pilot to becoming Leona’s steadfast partner, balancing professional diligence with quiet romantic admiration. He channels his affection into maintaining Bonaparte’s functionality rather than overt gestures, reflecting his patient, observant demeanor.

As threats escalate—from corporate espionage to rogue AI weaponry—Al’s role grows, confronting crises without compromising his loyalty to the Tank Police. Internal disputes and external demands for reform test the unit, yet his commitment to teamwork and adaptability remains unshaken. Consistent across his arc are his technical mastery, methodical professionalism, and understated yet pivotal contributions to missions.

Physically, Al presents a youthful figure with blond hair, blue eyes, and the unit’s standard uniform, augmented by tactical armor and a filtration mask during operations. His interactions center on his dynamic partnership with Leona and cooperative rapport with fellow officers, though his personal history beyond service is undisclosed in documented records.
