In 2025, the six members of what would become Manifest—Mina Solak, Lidya Pınar, Esin Bahat, Hilal Yelekçi, Zeynep Sude Oktay, and Sueda Uluca—were all winners on the
singing competition reality show
Big5 Türkiye, organized by the talent agency Hypers New Media. Among the selection jury was singer
Gülçin Ergül, formerly of the girl group
Hepsi. They subsequently underwent six months of training in singing and
K-pop-style choreography. Their debut single, "Zamansızdık", was released in February 2025 and accumulated over 12 million streams within a few months. They held their first concert the same month, at the Jolly Joker Arena in
Istanbul, and were joined onstage by Ergül. Their second single, "Arıyo", came out in April; it was followed by "KTS (Kalbimin Tek Sahibi)" and "Snap", both in May. In April, Manifest announced their first album,
Manifestival, which was released on 13 June 2025 and debuted at number one on the charts in Turkey and Azerbaijan. To support the release, they hosted a two‑day festival in Istanbul on 28–29 June, selling approximately 25,000 tickets, and followed it with a tour. In October, Manifest issued the single "RÜYA". In December, they released the single "Amatör". In February 2026, the single "Başrol Sensin (1. Yıl Özel)" came out. In April 2026, the single "Daha İyi" came out.
September 2025 investigation Following a 6 September performance at Istanbul's KüçükÇiftlik Park, Turkey's
public prosecutor's office launched an investigation into the group for "indecent and immoral acts" and "exhibitionism". On 6 October, the group was issued an indictment, which stated that their dance performances were deemed to have "harmed public morals, decency, and modesty" and to have "negatively affected children and young people". Prison sentences ranging from six months to one year were sought for the group members and for the guest performer Ayça Dalaklı, known professionally as AYDEED. The Istanbul 49th Criminal Court of First Instance sentenced each group member and AYDEED to three months and twenty-two days of imprisonment. The court later ruled for the suspension of the verdict for all defendants and lifted the previously imposed judicial control measure banning them from leaving the country. ==Band members==
