This narrative begins with the main character being betrayed and plunged into a treacherous dungeon, his sole objective being survival. However, as the challenges become less daunting, he loses his memories and grows complacent. Any thoughts of revenge fade, replaced by a disinterest in everything except his own well-being. His appearance changes, with white hair and a sleek black outfit, complete with a trench coat. Bored with his mundane existence, he decides to conquer every formidable dungeon, seeking reasons to aid others (even if the motives are flimsy), adopting a melodramatic teenager's stance on refusing help while going above and beyond to assist them. Along the way, an unintended harem forms, despite his lack of personality and seemingly cool exterior. In these dungeons, there's an absence of tension as he casually converses with his companions. When he encounters old acquaintances, his claimed detachment gives way to genuine surprise and concern. The entire story reeks of "SOA," a book symptomatic of a broader issue in Japan's light novel scene. Many readers have limited exposure to quality literature, encouraging authors to churn out numerous subpar novels catering to base instincts due to their ease of production.
