1.a middle school boy go to school along with his childhood friend , a girl who was 1 years older than him. She like a big sister and treat the boy like a kid but the boy actually have crush on her.

So at school, suddenly there is a mass of black alien shaped like monster flying and attacking the school. Many die and while the boy and the girl run, the alien throw a black ball energy and the girl pushed the boy so it only hit her. The boy crying thinking she was dead but suddenly she emerged naked, and when the alien want to attack the boy, the girl kill all of the alien with ease.

The girl hug the boy and uncapable of human speech, the boy realized she become a different person. The government come and tell the boy they have combating the black alien and tell the boy that the girl have turned into a monster and lose her humanity but she still have an emotion like love to the boy and she seems obeying the boy commands.

In the end the boy forced to join the government special elite obs, and his weapon is the girl itself. If the boy refused, the girl will be killed because she was to dangerous.

2. Another alien manga, about a girl been attacked by rabbit or bear doll costume. She thought there is a man inside but realized the bear and rabbit doll turned to hedious form and it was a monster. When she run, shr meet a boy who unzip his back and emerged a rabbit ot bear kinda forget what alien he is.... and he killed the alien that chased the girl. The boy reveal he was also alien and he saved the girl for some reason but now he is stuck in his alien form because his human skin is destroyed and dunno the rest of the story.
