I must admit that I can see why some people might not enjoy this novel, but there are points I strongly disagree with. It's not a revenge story; Hajime never explicitly seeks revenge. Although he momentarily contemplated it, his primary focus was to escape. He repeatedly expressed indifference towards his classmates, even considering himself heartless. However, he does eliminate any obstacles in his path, which could be seen as "shoot first, ask questions later." His initial kindness and consideration were indeed compromised, but it's understandable that circumstances would shape his actions. The complexity of human nature is portrayed here, as even helping Yue was prompted by her perceived betrayal.
The characters are well-developed, despite the light novel format, with distinct backgrounds and consistent personalities. The main character evolves throughout the story, developing feelings for his party members, which was expected. His harem is not an instant thing; he only accepts Shia after finding a way back to Earth, and Yue's influence played a role in that decision. They both recognize their mutual dependency.
While some might perceive Hajime's actions as contradictory, I don't think it is. His main goal was to return home, and he took on additional objectives like protecting others. His decision to help Yue was a deliberate choice, not a deviation from his original plan.
The exaggerated behavior in the story can be seen as a comedic exaggeration of not caring about the world, which balances out the serious themes. The novel is not overly dramatic but rather filled with humor, making it enjoyable despite its serious undertones.
The MC's breakdown is a powerful moment, but it's tempered by his reaction to eating a bear's arm, demonstrating that not everything should be taken seriously. The novel addresses serious issues like discrimination and manipulation, but often uses irony or parody to address them.
I've read the main novel multiple times and still find it funny. The after-story is even more entertaining, both in a good and a satirical way. The fact that the MC stands up for himself and isn't a passive protagonist is refreshing. Hajime's actions are not ruthless for the sake of it, but driven by purpose.
In conclusion, I wholeheartedly recommend this novel, especially if approached with a light-hearted mindset. It has a consistent plot and well-rounded characters, offering a humorous and straightforward story with occasional side quests that serve the main narrative.
