Official fan club "HYPSTER" members will be able to purchase exclusive merchandise to celebrate Rio Mason Busujima's birthday!

The 13th item is "Rio Mason Busujima" and comes with a "Hot Sandwich Maker (with recipe book)"!

We've prepared a hot sandwich maker, which is great for Rio, who often cooks outdoors!

Of course, it's a direct-heat type that can be easily used at home.

It features a cool design that allows you to brand Rio's MC name onto it.

As a bonus, I'll include a recipe book directly from Rio!

I imagine it's quite difficult to source unusual ingredients, but please do your best and try cooking them!

You can still purchase tickets if you join now.
