The Spider at the Top of the World - Episode 1

Lilian Moon faces humiliation when her summoning fails, producing only a weak Lower F-Rank Greywolf Spider, unlike others who summon powerful beasts. She tries to dissolve the bond, risking her own life since humans without beasts cannot survive, but her adviser warns of the grave consequences. Forced to stay bonded with the weak spider, Lilian suffers pain and confusion as she suddenly awakens inside the spider's body. Then, a mysterious System activates, granting her powers to evolve. Determined, Lilian vows to overcome her setback and prove herself despite the harsh judgment she endures.
