So I'm a Spider, So What?
Okina Baba
An ordinary high-school girl is reincarnated as a spider in a deadly dungeon after a mysterious explosion. With no help and surrounded by lethal monsters, she must survive using wits and an explicit in-world System: visible levels, skills, titles, and evolution tiers that turn survival into constant grinding. Each evolution and skill acquisition is a tangible power leap, making structured advancement the engine of the entire story.
Progression: Explicit System-driven progression: Levels, stats, skills and titles granted by the System. The protagonist evolves through defined monster stages (Small Lesser Taratect → Zoa Ele → Queen Taratect → etc.), each evolution a clear tier with new abilities. Skills level up with use (e.g., Appraisal, Thread Control, Poison Resistance) and can be acquired via skill points, with synergy and combination forming higher-tier abilities. Parallel human side shows conventional level-ups, emphasizing the quantitative ladder.
