Beast Soul: My F-Rank Worm Is the Primordial Dragon! - Episode 4

The protagonist struggles with his F-ranked Beast Soul compared to Nancy's powerful S-ranked soul, feeling hopeless. His Primordial Dragon soul awakens for the first time in 20 years and reveals its shattered state after a past battle, explaining why the protagonist's power is weak. To restore his strength, the dragon soul demands faith from the Four Divine Beasts' descendants. The immediate conflict arises as the protagonist must face a duel against a woman from the Vermilion Bird family, the first key to restoring power. A risky plan emerges: to establish a primal soul resonance with her, which might require an unexpected act—a kiss—to temporarily borrow her essence and gain strength for the upcoming match.
