Understanding Multi-Character Formats in Sanrio

Sanrio has developed many distinct multi-character entities across its history, from legendary twin duos such as Little Twin Stars (1975) to sibling trios like Goropikadon (1982), vast confectionery worlds like Sugarbunnies (2004), official revival teams like Hapidanbui (2020), virtual dance-vocal groups like Beatcats (2020), and psychological story casts like Maimaimaigoen (2021). These multi-character properties are not identical in structure: some are permanent pairs, others are large story ensembles, and units like Hapidanbui unite pre-existing characters who continue to operate as standalone powerhouses.

What Counts as a Sanrio Group, Duo or Unit?

To avoid confusing casual fans and collectors, Sanrio's multi-character properties must be classified according to their canonical structure, character origins, and commercial presentation. Below are the core organizational categories:

1. Canonical Duo / Pair

Two characters specifically designed and marketed together as a primary unified property. Examples: Little Twin Stars (Kiki and Lala), Patty and Jimmy, and Sugar Minuet.

2. Canonical Trio / Sibling Group

Three characters forming a permanent, indivisible team or sibling ensemble. Examples: Goropikadon (3 thunder-boy brothers) and Twee Dee Drops (3 rabbit boys).

3. Official Revival / Crossover Unit

An official team formed by gathering pre-existing standalone Sanrio characters under a new mission. Example: Hapidanbui (formed in 2020 with six classic male characters).

4. Music and Performance Group

An original character property centered on songs, choreography, dance teams, and virtual performance. Example: Beatcats (5-member cat dance-vocal group).

5. Multi-Character World

A vast fictional world populated by multiple distinct pairs and trade artisans. Example: Sugarbunnies (confectionery world of Bunniesfield with 14+ twin rabbits).

6. Narrative Story Ensemble

A large narrative cast whose core appeal lies in serialized interpersonal drama rather than individual mascot marketing. Example: Maimaimaigoen (17 core characters).

Hapidanbui: Sanrio's Official Boy Group Unit

Formed in January 2020, Hapidanbui (はぴだんぶい) represents one of the most innovative and commercially successful corporate initiatives in modern Sanrio history. The name stands for "Happy Danji V" (Boys Who Want to Become Happy), unified under the philosophy that "it is okay if you do not do everything perfectly; trying your best will make you happy."

The Six Canonical Members of Hapidanbui

Unlike fictional idol groups conceived from scratch, Hapidanbui unites six established classic male characters from the late 1970s, 1980s, and 1990s:

Pochacco (1989)

Vocals and Guitar Leader

Tuxedosam (1979)

Drums and Gourmet Connoisseur

Kerokerokeroppi (1988)

Accordion and Energetic Cheer

Bad Badtz-Maru (1993)

Vocals and Rock Bassist

Hangyodon (1985)

Bass, Tambourine and Heroics

Ahiru no Pekkle (1990)

Keyboards and Dance Specialist

The "V-Shaped Revival" Phenomenon: The formation of Hapidanbui triggered a massive resurgence for these characters. Hangyodon jumped back into the top 10 of the Sanrio Character Ranking, Pekkle enjoyed high-profile merchandise sellouts, and Pochacco solidified his status in the top 3 globally.

Beatcats: Sanrio's Music and Dance Unit

Co-developed in 2020 by Sanrio and Sega Toys, Beatcats is a virtual dance and vocal unit composed of five stylish cat characters. The project was created specifically to appeal to digital-native audiences through music streaming, TikTok dance challenges, anime shorts, and interactive mobile experiences.

The Five Canonical Members of Beatcats

Mia: The pink cat center who loves bright fashion and high-energy vocals.
Chelsea: The baby-blue cat with a gentle, chic personality who excels at soothing melodies.
Rico: The yellow cat full of athletic power, sharp dance moves, and acrobatics.
Layla: The purple cat with a cool, mysterious aura and hip-hop rhythm flow.
Emma: The mint-green cat, a soft-spoken foodie and fashion coordinate specialist.

The Beatcats lore centers on consuming human "dokidoki" (heart-throbbing emotional excitement) and converting it into dazzling stage performances and musical releases.

Maimaimaigoen: A Large Narrative Story Ensemble

Launched in October 2021, Maimaimaigoen (まいまいまいごえん) demonstrates Sanrio's versatility in psychological storytelling. It is neither a traditional mascot property nor a musical unit, but an intricate narrative universe told through serialized manga on Young Ace Up and an episodic RPG Maker game.

The 17 Core Characters of Maimai Dori

The story follows 16 young children from the Sunflower Class (such as Shin, Dial, Okada, Rin, Hikari, Hayato, and Kanata) and their well-meaning nursery teacher, Mamoru Okada (Sensei), who become trapped inside the surreal amusement park "Maimai Dori."

The children must confront moral dilemmas, emotional vulnerabilities, and park challenges to earn medals and escape. Its ensemble structure allows rich character dynamics that stand apart from conventional standalone mascots.

Classic Duos, Trios and Sibling Groups

Little Twin Stars (1975)

Twin celestial siblings Kiki (blue hair, curious younger brother) and Lala (pink hair, gentle older sister) born on the Omoiyari Star in the Dream Galaxy. They remain Sanrio's most celebrated canonical duo.

Goropikadon (1982)

Three mischievous oni thunder-boy brothers: Goro (blue hair, loves naps), Pika (pink hair, quiet nature lover), and Don (green hair, gadget inventor). A legendary 1980s Showa trio.

Patty and Jimmy (1974)

Sporty young girl Patty and studious chess enthusiast Jimmy living in Evanston, Illinois. A vintage American collegiate pair introduced in 1974.

Twee Dee Drops (1980)

Three energetic rabbit boys (Puck, Chippy, and Pip) who wear pirate-style hats and colorful pastel ears, playing daily games in their coastal homeland.

Group Member vs Standalone Sanrio Character

A key structural feature of Sanrio's branding is the relationship between individual characters and group units. For example:

Dual Identity Architecture: The Hapidanbui Example

When Pochacco, Tuxedosam, Keroppi, Badtz-Maru, Hangyodon, and Pekkle perform as Hapidanbui, they function as a single collaborative unit. However, they are NOT confined to the group:

Separate Ranking Ballots: In the annual Sanrio Character Ranking, fans vote for each character individually, not as Hapidanbui.
Independent Heritage: Each member possesses their own family lore, separate companion characters, and distinct debut decade.
Solo Product Lines: Individual merchandise lines continue alongside official Hapidanbui unit goods.

How Sanrio Group Concepts Changed Over Time

The philosophy behind Sanrio's group properties has evolved dynamically over fifty years:

1970s (Storybook Pairs and Rural Circles): Simple, elegant visual pairing emphasizing friendship, rural charm, and Americana (Little Twin Stars, Patty and Jimmy, Bunny and Matty).
1980s (Themed Trios and Sibling Dynamics): Colorful character trios with defined comedic personalities and sibling banter (Twee Dee Drops, Goropikadon).
2000s (Artisan Confectionery Universes): Expanding single concepts into vast multi-character vocational realms (Sugarbunnies, Sugar Minuet).
2020s (Crossover Units, Virtual Idols and Narrative Gaming): Assembling established legacy characters into empowerment boy bands (Hapidanbui), launching virtual dance groups (Beatcats), and crafting serialized psychological game casts (Maimaimaigoen).

Which Sanrio Groups and Units Are Still Active in 2026?

Sanrio's modern and classic group entities continue to maintain active schedules across multimedia channels:

Hapidanbui: Highly active in 2026 with new single releases, collaborative convenience store campaigns, live theme park appearances at Sanrio Puroland, and prominent placements in the 2026 Sanrio Character Ranking.
Beatcats: Regular music video drops on YouTube and TikTok, accompanied by official rhythm game updates and dance event pop-ups.
Maimaimaigoen: Ongoing manga serialization and new chapter releases for the official adventure RPG game.
Little Twin Stars: Celebrating major milestone anniversary campaigns with dedicated retro giftware lines and cosmetic brand partnerships worldwide.
