She continued, "I, Ichikawa Miori, will graduate from NMB48 this spring. Please excuse me for making this announcement in front of this crowd." She also thanked her fans, "During my 8 years as an idol, I had many chances and found many things worth living for. I can't thank you enough for the past 8 years. It's my life treasure to have joined AKB48 and NMB48 and to have met many of the members, staff, and fans. Thank you very much."
