My F-Rank Bug is the S-Rank Hive Queen Full Episodes

Evan, a slum boy, awakened the magical beast egg his mother had sacrificed her life to obtain. When it hatched, it revealed an underdeveloped ant queen named Alia, who was mocked as a useless bug. After forming a blood pact with her, he discovered that Alia was an S-rank Beast Devouring Ant Queen capable of consuming magical beasts and transforming them into an army of ants. After three days of hunting in the wilderness, Evan turned the tables at the academy trials, leading his insect army to victory and slaying an S-rank giant ape. The Walker family's persecution, dark magic in the dungeon, hellhounds, the abyssal beast Valhan, and a million-strong beast tide followed one after another. Evan and Alia eventually achieved symbiosis, defeated Valhan, and saved the Lower City. In the end, Evan earned citizenship in the Upper City and married Maya.
