Stealth under the moon sounds like it's about maybe... secret agents, commandos, spies or ninja, but "under the moon" feels quite poetic and gives it a bit of a historical or fantasy vibe, though the use of moon could also be sci-fi? Like it could literally be about a secret agent in space who sneaks onto a ship that's orbiting a moon or something?
Blessed Sakura is almost certainly romance and probably set in Japan. If I wanted to guess I'd say it's a story about like... somebody who falls in love with a shinto shrine maiden, and either sakura blossoms feature prominently (ie. it's set in or has some important scene set in spring) OR one of the main characters is literally called Sakura.
