Hikaru Takabe may not be the most social of teens. Always sporting her headphones, she gives off an aloof aura that rubs her classmates the wrong way. But her not being part of the crowd takes on a different dimension when she becomes involved in an intergalactic game of cat and mouse.

If you're experienced, you've read it all before.

The first two volumes aren't bad - the characterisation being solid enough - but the last two turn it into a nonsensical mess that would most likely leave you with a desire to have re-read Parasyte instead.

In terms of the 'merging' itself, 7BN has more in-common with  read more

Manga: Neon Genesis Evangelion
Both are science fiction stories that contain loner main characters that are forced to help save the world. Perfect for people who dig angsty protagonists.
