I always liked stories where people who were raised in cults or like human weapons try to reintegrate into normal society. It's a fun thought experiment on how their upbringing clashes with a standard culture. We're only a couple chapters in, but Hikari's actions are pretty interesting:
- Never complain about injuries and press on with your task.
- Cannot understand the idea of personal desires, just follow orders.
- Needs a 'master'.
Most manga tend to speedrun the healing process of people like this, but I personally hope Hikari's growth takes a while, since it would feel more natural after 10 years of mental conditioning.
I'm reminded of Full metal Panic, where Sousuke was raised as a child soldier before becoming a teenage mercenary and is tasked with going undercover as a normal high school student to bodyguard a girl in Japan.
And his normal "school supplies" include handcuffs, knives, tasers, pistols, and grenades, to name a few and he has basically zero idea how to act like a civilian throughout a large part of the series.
And, as I remember it, he only
sorta gets better, because he's experienced not just 10 years of mental conditioning, but also
physical and
emotional conditioning, from actually being a soldier and that doesn't go away in a scant year or so.
