Y’know how in One-Punch Man, Saitama usually gets involved with the plot either by complete accident, or due to a very stupid reason like wanting the world-ending monster army to quiet down cause the noise is bothering him?
That’s sort of how Raina is in this comic. As she is quite literally insane, she finds the incredible magic powers on display hard to distinguish from the hallucinations she already experiences daily, leading to situations where her reaction to a wizard kicking a magical robot assassain through the wall of her house is ‘slight indignation’.
It’s an interesting spin on the chosen one trope, because Raina is so uncaring towards her status that she’s rendered almost blind to the conflict going on around her. She doesn’t seem to be aware of the seriousness of the situation or her place in it, and makes reckless, extremely dangerous decisions as if she were planning a trip to the dentist. She’s abrasive towards the few individuals who do seem to care about her and scorns aid from people who others would kill to have at their service.
Despite this, it’s surprisingly hard to dislike her, because due to her psychosis she’s not fully convinced that the events happening around her are even real. For all she knows, Don Quijote, the Guarding House, and even the city itself could just be figments of her imagination. I mean, if you were assuming that the magical ghost sworn to protect you was just a hallucination borne of not taking your anti-psychotics, it makes sense that you’d want him to stay quiet and bother you as little as possible.
I thought the ending was also very solid. We never really learn the full intricacies of how the three houses work, but we don’t really need to, ‘cause it’s Raina’s story, and she doesn’t know or care regardless. Her part in the whole thing gets a satisfying conclusion, and that’s what really matters.
