Second season of Tsukiuta. The Animation.

Nasa Yuzaki is determined to leave his name in the history books. Ranking first in the national mock exam and aiming for a distinguished high school, he is certain that he has his whole life mapped out. However, fate is a fickle mistress. On his way home one snowy evening, Nasa's eyes fall upon a peerless beauty across the street. Bewitched, Nasa tries to approach her—only to get blindsided by an oncoming truck. Thankfully, his life is spared due to the girl's swift action. Bleeding by the side of an ambulance, he watches as the girl walks away under the moonlight—reminiscent of Princess Kaguya leaving for the moon. Refusing to let this chance meeting end, he forces his crippled body to chase after her and asks her out. Surprised by his foolhardiness and pure resolve, the girl accepts his confession under a single condition: they can only be together if he marries her! [Written by MAL Rewrite]

Second season of Space Dandy. Space Dandy is a dandy guy, in space! This dreamy adventurer with a to-die-for pompadour travels across the galaxy in search of aliens no one has ever laid eyes on. Each new species he discovers earns him a hefty reward, but this dandy has to be quick on his feet because it's first come, first served! Accompanied by his sidekicks, a rundown robot named QT and Meow the cat-looking space alien, Dandy bravely explores unknown worlds inhabited by a variety of aliens. Join the best dressed alien hunter in all of space and time as he embarks on an adventure that ends at the edge of the universe! (Source: Bandai Visual)

The universe is a mysterious and strange place, full of even stranger and more mysterious aliens. Dandy's job is to hunt down unclassified aliens and register them for a reward. It sounds easy enough, but something weird always seems to happen along the way, like chance meetings with zombies, mystical ramen chefs, and adorable orphans. Hunting down aliens may not be easy, but it's definitely never boring. With the help of his sidekicks, the adorable robot vacuum QT and cat-like alien Meow, and his slightly-used ship the Aloha Oe, Dandy roams the galaxy searching for new alien species. What he usually finds, however, is adventure, danger, and romance, and no two journeys (or universes) are ever the same. This is Space☆Dandy, baby!
