TM Chapter 46

Invasion (侵攻, Shinkou) is the sixty-sixth chapter of the Trigun manga. It is also the forty-sixth chapter of Trigun Maximum.

Summary
The Ark causes a populated bridge to collapse, as Knives and Legato witness Vash perform his exercises. This perplexes Knives as he thinks that if Vash's joints and muscles were discombobulated he'd still be able to move. The topic then changes to how over 150 years Plants have been exploited by humans.

Soon an unknown militia tries to contact the ARK warning that it has entered a prohibited zone. Just when the militia planned to shoot down the Ark, they're confronted by Wolfwood, Chapel, and Livio. Wolfwood fires a single rocket at the militia barely killing any of them which Chapel criticizes him in a humored manner. Livio then slaughters the remainder of the militia and Chapel notes that they've been emancipated from their torment.

Back on the Ark, Vash debates with Knives on how humans can change, despite what they did to Tesla, though, Knives remains obstinate.
