While fans expressed their shock with comments like “No way!

AMEFURASSHI's fans, known as “Colors,” shared messages of strong determination, saying, “It's our mission as Colors to continue spreading the charm of the four until the very end” and “We will just support them with all our might for the time remaining.”

The groups' talent was also highly praised, with comments such as “Their visuals, singing, and dancing are all top-tier” and “They deliver live performances too good for such a scale.” Fans lamenting the disbandment also revealed complex feelings towards the management agency, stating, “There's no way the agency should discard such a group” and “It's wrong for these girls not to shine.” Additionally, some speculated on the harsh realities of the idol industry, remarking, “Being an idol is tough, isn't it?” and “I wonder about Stardust's financial situation.”

A post that perfectly encapsulated the sentiment read: “While watching the lively discussions of artists confirmed for Kohaku Uta Gassen on NHK's Akashiya Kohaku, I suddenly checked X and saw the disbandment announcement for ukka, AMEFURASSHI, and LumiUnion. It's become a year-end where I'm truly pondering the meaning of 'mixed emotions.'” This highlights how the disbandment news, coming amidst the success of other idol groups, has sent significant shockwaves through the hearts of fans.

With the groups' final activity dates just months away, fans are vowing to support them until the very last moment and create cherished memories, saying, “I want to say thank you without regrets” and “Let's meet Amefura-chan many times and make fun memories.” The members themselves have also released positive messages about moving “to a new stage,” and fans are preparing to witness their final performances while looking forward to their future endeavors.

The context

Stardust Promotion is one of Japan's largest talent agencies, managing numerous actors, models, and idol groups. Japanese idol culture involves a deep connection between idols and their fans, who invest significant emotional and financial support. Disbandment, especially when sudden or for highly-regarded groups, is a major event that can deeply affect the fan base, often leading to strong emotional reactions like those seen here. The mention of 'Kohaku Uta Gassen' refers to NHK's annual New Year's Eve music spectacular, a prestigious event that symbolizes significant success for a music artist.
