F-Rank Awakening: He Who Commands the Legendary

In a beast-summoning world, Francis Cobb's girlfriend, Rita Lowe, frames him and dumps him during a summoning ritual, leaving him with only an F-rank Shadow Cat. Unexpectedly, he awakens the Divine Beast Taming System. His cat evolves rapidly, and even the legendary Devourer bows to him. Rita becomes a Prodigy, but little does she know that the ex-boyfriend she once deemed a loser has already become an Anomaly.
