I don't know how Takahiro sensei does it, but his action writing is really really good.
Majikoi's battles weren't that exciting but he's only gotten better over time.
Akame Ga Kill's battles were really fun and dynamic.
Mato Seihei's battles are hype as fuck.
The battles in Hell's Tormentor Kraken are edge of your seat, blink and you miss it strategy. Like... it respects the intelligence of the reader. Mad respect to this guy.
