Yes, Master Mosquiton is a great OVA series! It's a bit of a hidden gem, but it's definitely worth checking out if you're a fan of stylish anime with a good sense of humor. The series follows the story of Yurine Himekura, a young girl who is obsessed with becoming immortal. She makes a deal with a vampire named Mosquiton, who agrees to help her find a legendary artifact called the O-Part, which is said to grant eternal youth and beauty. Along the way, they are pursued by a variety of enemies, including the government and a rival vampire clan.
Master Mosquiton is full of great action, comedy, and romance. It's also a surprisingly thought-provoking series, exploring themes such as the nature of immortality and the importance of living in the moment.
If you're looking for a fun and stylish anime series to watch, I highly recommend Master Mosquiton. It's available to stream on Crunchyroll.
