Snackgirls editorial note
Kirari: The ice-cream-parlor visual makes this feel like a very summer-friendly karaoke collaboration.
AIKO: Check the campaign dates, participating shops, room surcharge and benefit stock notes before making a plan. Product and drink prices should be checked again on the official page before buying.
Karaoke Manekineko has launched the Nijisanji “Sweet Scoop Sundae” collaboration campaign. GAME Watch’s July 15 evening report also summarizes the rollout and the new visual goods.
The campaign runs from July 15 to August 16
According to the official campaign page, the collaboration runs from 13:00 on July 15, 2026 through August 16.
The featured livers are Joe Rikiichi, Hanabatake Chaika, Mashiro Meme and Ryushen, with a summer ice-cream-parlor theme that fits a karaoke-room visit and merch pickup.
Drinks, goods and singing campaign are bundled together
The official page separates the package into collaboration drinks, goods, a singing campaign and other campaign notes.
Drink orders are guided through Manekineko’s app flow, and the page also warns that benefits may end once stock runs out. Check the current product and drink price display on the official page before visiting or ordering.
Collaboration rooms need a separate reservation check
Selected shops offer collaboration rooms, and the official note says phone reservations are not accepted.
The room note lists a surcharge of 1,500 yen per person on top of the normal room fee, with late-night slots handled against the free-time room fee. Store-by-store conditions still matter.
Why this is worth watching
The appeal is not just online goods. It is an offline VTuber collaboration that connects karaoke space, drinks, goods and a singing campaign.
The takeaway is a Nijisanji event route that remains active through mid-August. Participating-shop coverage and benefit stock will decide how easy it is to enjoy.
