Strictly speaking, the LapXas-13 is an improved version of the U-KTU-19. The LapXas Submarine Research and Manufacturing Company discovered detailed blueprints of the U-KTU-19 attack submarine at an abandoned military outpost. Company researchers believe that this hull design, similar to surface naval vessels on Earth, allows the submarine to more easily combine reliable transport capabilities, firepower, protection, and propulsion. The LapXas-13 prototype, LapXas-T, is equipped with two Panence-15 nuclear fusion reactors and two Imaya fusion engines. A captain named Franz customized the first LapXas-13, and to show goodwill, LapXas designated it as LapXas-F-13. Under Captain Franz's command, the LapXas-F-13 successfully completed numerous missions without a hitch. After discussion among several nuns, the full crew, and Captain Franz, the LapXas-F-13 was named -WolfMaria-
: her gentle jade-like hands exuded a fragrance as intoxicating as mother's milk, embracing children on the cruel world of Jupiter II with kindness; Maria's legs were delicate and graceful, but even when her path was filled with ice spikes, she would break through obstacles and safely bring the children back.
The LapXas Submarine Research and Manufacturing Company reminds you: the LapXas-13 is still technically in a state close to that of a prototype.
