Kiseijuu: Sei no Kakuritsu Scans
I like the OP, the ED's nice too; really chill and balances out the OP. Migi is really funny. I find it kind of nice that Migi wants to co-exist with Shinichi instead of straight up wanting to control or kill him as much as some of the other Parasyte's we meet. It'll be interesting seeing Izumi & Migi's relationship develop over time. Shinichi got pretty badass about halfway into the series, but kinda detached as well.
Overall this series was awesome \o/
