Tamagotchi × L’Arc-en-Ciel Larkutchi Z 1998 Limited Edition Collaboration Item

There exists a “special Tamagotchi” that feels like the 90s frenzy has been sealed inside your pocket. That is the limited model “Larkutchi Z,” born from a miraculous collaboration with a hugely popular rock band.
Its distinctive design—a black heart with wings—has a presence that feels completely different from standard versions. And because it was sold only back then with no reissue, it’s a brutally rare item for collectors.

In this article, we’ll explain the appeal and value of this “phantom” collaboration Tamagotchi in a way that’s easy to understand even for first-timers.

Shape / Design

A red heart-shaped body with white angel wings. This is the origin of the series, balancing cuteness with that unmistakable “L’Arc feel.”

Release Period / How It Was Sold

Contents (What You Can Do)

A mini-game where you raise the “love level” of the cat couple Raruko and Raru-o.
The goal is to reach 100% affection, so it leans more toward a romance mini-game than classic pet raising.

Larkutchi Z (1998 / 2nd Model)

Shape / Design

A black heart-shaped body with black devil wings. It’s designed as a darker counterpart to the first model (angel).

Release Period / How It Was Sold

Shape / Design

An orange-toned heart paired with black devil wings. The color scheme feels like a blend of the first model’s red and Z’s black—an “in-between” image.

Release Period / How It Was Sold

Sold in 1998 as live merchandise during the second half of the same “Haruto Hi o Tsukero!” tour.

Contents (What You Can Do)

A game where you help a hippo lose weight.
It includes a pedometer function—the more the owner walks, the more the hippo slims down.
Rather than pure raising, it’s best described as a Tamagotchi + step-counter toy.
