The Idolmaster SideM continues its impressive run of collaborations, and this one is genuinely delightful: Bandai Namco is teaming up with Aoyagi Souhonya (青柳総本家), a historic Nagoya sweets maker, for a limited-edition collaboration of their iconic kaeru manjuu (frog-shaped steamed buns) featuring Pierre.

What's It About?

This collaboration is part of the "Deramas" (でらます) project — a local initiative by Nagoya-based companies and tourism organizations to promote regional culture through SideM content. The collab pack will be available from August 3 through September 16 at Aoyagi Souhonya's Otsu Honten (main store) in Nagoya's famous Otsu district.

What You Get

  • "Kaeru Manjuu: Deramas Collaboration Pack" — the classic frog steamed buns in special Pierre packaging
  • Original novelty item included with each purchase
  • Paper craft on the back of the box — so you can build a little Pierre frog manjuu for photo ops!

Aoyagi Souhonya has been a Nagoya institution since 1869, and their kaeru manjuu is arguably the city's most recognizable sweet. The idea of Pierre — the serious, dignified idol who's also secretly a total foodie — in frog bun form is just adorable.

Why This Is Cool

Deramas has been one of the more creative local collab projects for SideM, bridging idol culture with Nagoya's real-world food scene. Previous Deramas collaborations have included menu items at local restaurants and themed shops across the city. This frog manjuu pack is the latest in that line, and it's a great example of how the franchise leverages regional partnerships.

If you're in the Nagoya area, this is worth a visit — both for the manjuu and for the whole Deramas experience. If you're not, keep an eye out for potential online sales or future Deramas collaborations.

Honestly, a frog manjuu with Pierre on the box sounds like something I'd actually buy. The Deramas collabs always bring that perfect blend of idol charm and real regional culture — it's one of the things that makes SideM feel special, you know?
