Ridiculed for summoning a flea, Natalie is pressured and insulted while rivals mock her and threaten her pet. The flea then activates Prickly Field, sending the crowd into uncontrollable itching; some tamers' beasts even attack their masters, yet Natalie remains unaffected, which alarms others. A reincarnated divine beast tamer—an Ashen Scion—reveals they can use the Soulforge Rite to gain power but need a stability elixir. Hungry, the flea is offered the tamer's blood on their arms and legs, but it suddenly bites elsewhere, breaking the agreement and leaving the scene spiraling toward an unknown threat.
