The Celestial Records speak of the existence of the "Seraphim," a race of divine beings who give blessings to humanity and are offered prayers by them in return. Those who are anointed with the ability to interact with these spirits are known as "Shepherds." Hailed as heroes for their prompt appearances in times of crisis, while also being feared for their power, the Shepherds are imprinted in common folklore along with the Seraphim. Sorey is a young human who has spent his entire life living in harmony alongside the Seraphim in the village of Elysia. Fascinated by the myths of the Celestial Records, he explores some nearby ruins with Mikleo—his childhood Seraphim companion—hoping to enlighten himself about the Seraphims' history with mankind. Unfortunately, they become trapped in the depths of the historical site during their investigation. While searching for an exit, they come across a mysterious girl who desperately seeks the help of a Shepherd to save the world, which is on the brink of being consumed by darkness. Despite Mikleo's warning about making contact with other humans, Sorey decides to help the stranger, which unknowingly leads him closer to the dream of peaceful coexistence between man and Seraphim.

The second season of Tales of Zestiria the Cross.

Thirty-seven-year-old Satoru Mikami is a typical corporate worker, who is perfectly content with his monotonous lifestyle in Tokyo, other than failing to nail down a girlfriend even once throughout his life. In the midst of a casual encounter with his colleague, he falls victim to a random assailant on the streets and is stabbed. However, while succumbing to his injuries, a peculiar voice echoes in his mind, and recites a bunch of commands which the dying man cannot make sense of. When Satoru regains consciousness, he discovers that he has reincarnated as a goop of slime in an unfamiliar realm. In doing so, he acquires newfound skills—notably, the power to devour anything and mimic its appearance and abilities. He then stumbles upon the sealed Catastrophe-level monster "Storm Dragon" Veldora who had been sealed away for the past 300 years for devastating a town to ashes. Sympathetic to his predicament, Satoru befriends him, promising to assist in destroying the seal. In return, Veldora bestows upon him the name Rimuru Tempest to grant him divine protection. Now, liberated from the mundanities of his past life, Rimuru embarks on a fresh journey with a distinct goal in mind. As he grows accustomed to his new physique, his gooey antics ripple throughout the world, gradually altering his fate. [Written by MAL Rewrite]
