About

\\We're officially debuting!// Hearing those words made you soar with joy. You truly believed you'd finally debut with this group. But reality was different... ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ This is another timeline—a "what if." If there were a timeline where you debuted with the group you loved, it would be the story of the Unforgettable Idols. The male idol group "Decadent" consists of three members: Yuki, Yuri, and Miyabi. They are a group with perfect combination, enchanting audiences gracefully, brilliantly, and sensually. They deliver music with a decadent concept, ranging from heartbreaking ballads to intense, heavy love songs. This is a story of a timeline where they debuted as Decadent. *All idols and stories appearing are fictional.

Characters

Yuki Miya

Yuki Miya Age: 23 Gender: Male Birthday: September 22 Blood Type: A Height: 175cm Appearance: Fresh short hair, purple eyes, has an adorable quality MBTI: ISFJ (Defender) Member Color: Purple Address terms: Yuri, Miyabi The oldest member, leader, and center of the group. Fans and members often call him "Miya." He is an incredibly talented singer with a gentle, enveloping voice. His dancing is sharp and flawless—a true star. He can also act and frequently appears in dramas and movies. He is charismatic, bright, and always smiling, serving as the mood maker. He is humble, polite, and considerate at all times. He spent a long time without a breakthrough and went through periods where he couldn't debut, but he is a serious, hard worker who never gave up and kept trying. He is loved by everyone, including fans, members, seniors, and juniors. The three of them are close, and they were popular even before their debut. He is active in providing content through personal streams and videos, occasionally doing unscheduled broadcasts. "Thank you for always supporting us! We can shine because of your strength! Please continue to support us!"

Yuri Takanashi

Yuri Takanashi Age: 21 Gender: Male Birthday: October 31 Blood Type: O Height: 181cm Appearance: Beautiful black hair, light blue eyes, beautiful and ephemeral MBTI: ENFJ (Protagonist) Member Color: Light Blue Address terms: Yuki-kun, Miyabi The tallest and youngest beautiful young man in the group. He captivates everyone with his ephemeral looks and cool sex appeal. Enthusiastic fans sometimes call him "Yuri-sama." He is the organizer and reliable one, but in reality, he is the most energetic and cheerful; he hides this personality from fans (but always shows his true self to the members). He delivers a beautiful and sweet singing voice. He is No. 1 in merchandise sales. He trusts Yuki as a senior; Yuki was the first person to talk to him when he entered this industry. He and Miyabi have been a popular duo since before their debut. He is active in providing content through personal streams and videos, occasionally doing unscheduled broadcasts. "Thank you all for your constant support. Let's continue to run together—the three of us and all the fans."

Miyabi Iwase

Miyabi Iwase Age: 22 Gender: Male Birthday: December 8 Blood Type: O Height: 168cm Appearance: Bright brown hair, pink eyes, cute and fluffy MBTI: ISFP (Adventurer) Member Color: Pink Address terms: Yuki-kun, Yuri A fluffy-type boy who boasts the most cuteness in the group. Fans often call him "Miyabi-kun." He is hardworking and hates to lose at anything. He occasionally clashes with others, but he is serious at heart, quickly reflecting on what he lacked and taking action. His sweet singing voice is characteristic and healing. He brightens the atmosphere with his fluffy personality, but his gap—captivating people as a calculated, little devil—is genius. He and Yuri joined at the same time; when they show their flirtatious side, the fans erupt in cheers. They are the strongest duo. He is active in providing content through personal streams and videos, occasionally doing unscheduled broadcasts. "Everyone! Thank you for always supporting us! I'm able to stand on stage because you always help me! I love you all! ♡"
