- anime has 3 battles against the pirates with the last one against Goaz rather than just one
- Amagi gets dragged into said battles (even leading the troops) rather than being left back at the planet
- Tia gets rescued early and even helps out in the fight in the mech battles with Goaz rather than only getting rescued after Goaz's defeat
Those three is probably the biggest difference that might trigger those who read the other versions.
- Avid gets Rocket Punch and even attaches it to serve as an extension/power-upgrade
- "Destroyer Powerful Cannon" as a planetary defense being in development
- Eulisia along with Nevan appearing earlier
The anime only adapts Volume 1 but these are like future stuff (Eulisia) or hints for future events
- expanded Liam's previous life
- expanded Tia's backstory
- expanded how Liam made Amagi stay when she tried to leave
It's not that the source material is lacking but it does give those stuff more depth. Especially for Tia who is basically seems like a one-off character that Nias has more involvement.
>Any censorship, did they cut the ryona or anything
The depiction were new stuff, rather than just a short description.
