2.5D Idol VTuber Unit 'Rabipare!!' to Host Super Large-Scale Event 'Buinone Utagoe Relay vol.4' Featuring Major Agencies on Saturday, June 13th!

Blackbox Inc. (Headquarters: Shinjuku-ku, Tokyo; CEO: Ryuyu Sakamoto), which operates the 2.5D female idol VTuber production 'Lovebox,' is pleased to announce that its first-generation unit 'Rabipare!!' will host the YouTube song relay event 'Buinone Utagoe Relay vol.4' on Saturday, June 13, 2026, starting at 16:00, featuring a total of 12 luxurious performers.

The previous 'Buinone Utagoe Relay vol.3' achieved significant success, trending on X (formerly Twitter) due to popular response and being covered by media news, leaving a significant mark on the virtual music scene.

The fourth installment, representing further evolution, will deliver an even more powerful lineup of performers.

■ Luxurious Talents to Perform! From Major Agencies to Skilled Independent VTubers

This event aims to foster interaction among VTubers beyond agency boundaries and to revitalize the virtual music scene. This time, members connected by 'music' will gather across genres, ranging from artists affiliated with major agencies that lead the VTuber industry to skilled independent VTubers who captivate fans with their overwhelming singing abilities.

Through a relay format across each talent's YouTube channel, we will connect their outstanding performances, where their individual charms shine, non-stop.

The theme for this event is 'Songs to Deliver to Loved Ones.' A total of 10 acts will sing their heartfelt emotions through their melodies, directed towards listeners and fans beyond the screen, and the 'loved ones' in their hearts.

■ From Online to Real! What is 'Rabipare!!', the 'Idol VTubers You Can Meet'?

'Rabipare!!,' the organizer, is a duo idol unit whose name is derived from 'Love + Vivid + Palette.'

Its most distinctive feature is the '2.5D Hybrid Style' that allows fans to meet them not just on screen but also in real life.

While leveraging the strengths of 'virtual' activities such as daily streaming on YouTube, their core activities involve performing live on real stages in their 'real appearances.'

This event will push the online excitement to its peak, and with that momentum, they will pass the baton to their next major stage: a solo offline live concert scheduled for Saturday, July 11th, the following month, in Shinjuku.
