Art: If I didn't know beforehand I'd be sure this is a Heroaki manga. It's realistic and detailed while also rough, sketchy and very dynamic with plenty of violence to spice things up.
Characters: bare minimum is there and it doesn't get in the way cause this isn't a manga where you need deep and complex characters. There are some awkward attempts to flesh then out but those are rather nice and brief.
Story: genetically modified soldiers, international spies, politics and terrorism are thrown together at random to make sense of like a teenage girl with inhuman power and cat claw blades (?) fighting a Chinese spy and three Russian super soldiers on top of a train. Near the end it gets a little more sensible and there's a lead into rogue government agent using metal gear tier technology to destroy the world and some mentions of Chinese mythology. I actually wanted to see what will happen next but too bad.
I guess it's worth mentioning there's a fairly generic romantic subplot where some guy treats our main heroine like a human which makes her kokoro go doki-doki but this is rather inconsequential too
Funfactor: I think this is worth reading for pretty cool action. The whole thing is just two volumes so it's not a huge time investment anyway.
