🔥 KEY MOMENTS

⚠️ Spoiler Alert!
1

The Photo Album Mystery

While flipping through Rei's childhood photos at her house, the Kimengumi crew and Yui and Chie notice the same boy appearing in every single picture beside Rei — a persistent ghost from her past none of them recognize.

2

Don Harumage Arrives

Rei's childhood best friend Don Harumage transfers into Class 6 out of nowhere, instantly rekindling old memories. His attempts to reconnect with Rei clash with the reality that her world now revolves around the Kimengumi.

3

Jealousy Creeps In

Don watches Rei laugh and bicker with the Kimengumi from the sidelines, visibly struggling with a cocktail of nostalgia and envy. His inability to slot into the group's chaotic dynamic starts to isolate him.

4

Pochi the Storm Creature

A sudden storm throws Don and Rei together, and they stumble upon a bizarre horseshoe crab-like creature they affectionately name Pochi. The discovery becomes a rare moment of genuine bonding that echoes their childhood friendship.

5

Pochi Goes to School

Bringing Pochi into the classroom predictably spirals into pure Kimengumi chaos, with students reacting in increasingly absurd ways to the strange pet. The situation turns the whole class upside down and gives Don his first real taste of life inside the Kimengumi orbit.

📍 ARC CONTEXT

Sitting at the season's midpoint approach, Episode 5 pivots from Episode 4's time-travel shenanigans to introduce Don Harumage as Rei's childhood rival, expanding the cast and adding a fresh comedic foil. This marks a transition point in the season, shifting focus toward rivalry and friendship dynamics that are poised to develop across the back half. It builds on the group's established chemistry while planting seeds for new conflicts and character development in the episodes ahead.
