It kind of strike me....
Insane troll logic warning:
War = Hell
and
Being surrounded by girls = Paradise/Heaven.
where
in IS-verse.... girls rules....
Therefore....
Better to reign in Hell (being like a real Man and get very good at war), than serve in Heaven (being submissive to the girls)?
Random idea stuff...
Spoiler for Mad science:
The real motivation behind the entire IS project was surprisingly not to make a Spacesuit but.... a flying jetpack.
The one who started the whole thing is just sick of tired of the lack of "futureness" (If you are born in certain generation, you should know what he mean by lack of futureness in the modern era
).
Due to the common complain of jetpack not being "safe", so the team keep adding safety feature into it and one thing lead to another (just like how the Portal gun is invented) and they end up with a spacesuit.....
Infinite (ability to fly forever) Stratos (ability to fly up to Stratosphere and stay there..... because it is the future, future means overcrowding and everybody should live in floating houses or stratosphere height sky-riser)
The mad man also kick-started various project the borderline mad-science level. Infinite Stratos was one of them unfortunately he also happened to kick the bucket before he get to see one of his dream come true.
