Title: Beast Master: Live Life to the Fullest!
Synopsis: Ash Bloom, a 21st-century female office worker and avid gamer, wakes up one morning to find herself back in high school. But this isn't the high school she remembers! Instead of math and history, she's stuck learning about Spirit Beast Evolution and how to become a Beast Master. Oh, and she's somehow missed the memo that humans and magical creatures called Spirit Beast coexist in this world.
As she tries to wrap her head around spirit energy, soul bonds, and a textbook that reads like a fantasy novel, Ash realizes she's now in a world where becoming a Beast Master is the ultimate goal. Struggling with no memories from the original owner of her body, she's left to figure it out on her own!
Now she just has to pass her tests, bond with a Spirit Beast, and somehow blend in without looking like she's just fallen out of a different dimension. No pressure, right?
Note: Slow-paced story with no romance plot.
