Haruka naru Toki no Naka de: Ryugu no Miko × GRATTE Collaboration Starting May 28!

遙かなる時空の中で 龍宮の神子 × グラッテ 5月28日よりコラボ!

28 May 2026 – 28 Jun 2026

Fans of the long-running romance adventure series Haruka naru Toki no Naka de have something exciting to look forward to this summer! Starting May 28, 2026, a special collaboration is kicking off between Haruka naru Toki no Naka de: Ryugu no Miko and GRATTE, running all the way through June 28, 2026. That gives you a solid month to make plans and get yourself to the event. GRATTE is a collab café brand known for themed food and drink experiences, so this is a great opportunity to immerse yourself in the world of Ryugu no Miko in a fun, atmospheric setting. Whether you're a longtime fan of the series or just curious about the collab café scene in Japan, this kind of event tends to draw dedicated crowds, so you'll want to plan ahead. The collaboration runs for about four weeks, giving visitors a reasonable window to attend, but don't let that lull you into a false sense of security — popular collab cafés can get very busy, especially in the opening days. Keep an eye on official announcements from GRATTE for details on menus, merchandise, and how to secure a spot.
