👀 SPOILER-FREE SUMMARY

A high-energy series premiere that wastes no time throwing its protagonist into one of anime comedy's most absurd premises. Iruma Suzuki, a pushover kid with terrible luck, gets sold to a demon and enrolled in a school full of creatures who'd eat him alive — literally. The tone is bright, fast-paced, and unapologetically silly, leaning into slapstick and fish-out-of-water humor from the first scene. Sullivan is immediately endearing as the overly affectionate demon grandfather nobody asked for, while Asmodeus Alice makes a strong impression as the first real test of Iruma's survival instincts. Expect a colorful, warmly animated introduction to the Netherworld that prioritizes charm and comedy over world-building dumps. The episode establishes identity concealment and adaptation as core tensions without ever feeling heavy.

🔥 KEY MOMENTS

⚠️ Spoiler Alert!

Sold to a Demon

Iruma's deadbeat parents literally sign him over to the demon Sullivan for cash. Instead of devouring him, Sullivan reveals he just wants a grandson to spoil rotten — instantly flipping the premise on its head.

Welcome to Babyls

Sullivan enrolls Iruma in the demon world's most prestigious school and lays down the one rule that matters: if anyone discovers Iruma is human, he'll be eaten alive. No pressure.

The Forbidden Speech

Forced onstage by his doting grandpa-principal, Iruma reads what he thinks is a normal entrance speech — only to accidentally recite a powerful forbidden spell that sends the entire student body into awe and submission.

Asmodeus Throws Down

The top-ranked first-year Asmodeus Alice, furious at being upstaged, challenges Iruma to a duel on the spot. Iruma's survival instincts and dodging ability — honed from years of avoiding his parents' schemes — let him accidentally win.

A Demon's Loyalty

Defeated and humiliated, Asmodeus does a complete 180 and pledges unwavering loyalty to Iruma, becoming his first devoted follower. Iruma's school life is already spiraling out of control before classes even start.

📍 ARC CONTEXT

As episode one of twenty-three, this is purely foundation — introducing Iruma's predicament, the Netherworld setting, and the central dynamic of a human hiding among demons at Babyls Academy. It establishes the key relationships with Sullivan and Asmodeus that will anchor the entire first season. Everything here is setup for a longer arc of Iruma carving out a place for himself in a world where simply being discovered could be fatal.
