Harry is a hedgehog living in modern Shibuya who describes himself as "adorably cunning." He actively seeks attention by cultivating a self-aware persona characterized by a blend of narcissism and performative charm, projecting an image of calculated cuteness.

Contrasting this persona, he exhibits significant timidity and a pronounced victim mentality. This creates internal conflict as his desire for admiration clashes with his frequent nervousness and self-doubt.

He maintains relationships within a group of animal companions centered around Hachi. He interacts regularly with the adventurous dog Hachi, the perpetually sleepy cat Mike, the fashionable dog Nana, the philosophically inclined crow Kuro, and the wise Moyai statue. His role in this group often involves comedic interactions arising from his personality contrasts.

His experiences include recurring challenges like job hunting, where he faces repeated failures. These narratives explore his persistence despite setbacks. Episodes focus on his escapades, such as being chased, seeking help, and dealing with daily obstacles in Shibuya.
