I think Nacchi's AKB48 career peaked in the 1ji59fun / Romance Irane era where she actually got a lot of exposure. She's a great vocalist, but we barely get to any of her. She was known for being one of the funny members along with Nonti, but in AKB48's current line-up she doesn't really manage to stand out with her image. Idk, I really don't know what AKB48 has yet to offer for Nacchi and how she sees her own future. I think she has plenty of talent... maybe she could pursue the musical circuit.
