Weapons, girls, and psychotics! That’s exactly what you get from watching Canaan.
Ultimately, the whole anime is based around Alphard trying to hunt down and kill Canaan as Canaan’s friend Maria is targeted, Canaan spends much of the story saving Maria over and over again. Maria is a cute, unhurt, happy girl that is pretty much the complete opposite of Canaan. Which ultimately makes the series feel a bit off.
