This one is a decidedly more lighthearted take on sci-fi, dug up from the dregs of the CMX library.
SUIHELIBE! (Suieribe!), by Naomi Azuma. First published in 2006 and first published in North America in 2008.
PLOT:
Tetsu just wanted to join a club, but when he pokes his head into the biology club's classroom, he finds a cute girl climbing out of a crashed UFO. This is Lan from the planet Noid, who needs to capture a variety of escaped alien lifeforms so she can graduate. The student council are all too ready to shut down the biology club due to its lack of members, so it's up to Tetsu and Lan to convince others to join them all while capturing more alien creatures and trying (and failing) to keep Lan's identity a secret.
