Tower of Etruria

Albion, a knight on a mission to rescue a princess from a witch, walks into a monster-filled tower. Classic fantasy setup, except this is a 2-episode hentai OVA where the knight, Albion, ends up in some very unorthodox situations while trying to actually complete his mission. The tower belongs to the witch Etruria, and it's packed with creatures ranging from a bumbling, inexperienced beholder to a ninja spy named Palmyra and a deadly seductress called Sirena. Every floor is basically a new problem, and Albion has to drag Princess Cecelia through all of it while the two of them figure out how to not get killed — or distracted — long enough to escape. The tone leans comedic more than dramatic. These aren't intimidating villains so much as chaotic obstacles, and the show leans into that awkward, almost slapstick energy. If you've seen Queen's Blade or Bikini Warriors, you know the genre — fantasy aesthetic, light action, adult content woven into the adventure framing. It's closer in spirit to Tower of Druaga if that game had taken a very sharp left turn. At two episodes, it doesn't overstay its welcome. It's a short, goofy romp through a monster tower with a knight who's in way over his head and a princess who's less helpless than she looks. Niche, yes. But if that specific flavor of comedic fantasy hentai sounds like your thing, this delivers exactly what it promises.
