The summer you gave meieiri reo

Leo Ieiri is a singer-songwriter from the music school Voice, known for producing YUI, who influenced her.

It appears she returned as an enrolled student in 2021.

While songs with the punch of her 2012 debut track “Sabrina” are memorable, she also has many pieces that depict adolescent emotions, and she captivates listeners with a blend of steadfast strength and delicate expression.

In particular, the fragility of her ballads resonates in a way that’s compelling precisely because of her transparency.

Selected as the theme song for the Monday 9 p.m.

drama Koinaka, “Kimi ga Kureta Natsu,” released in 2015, is a mid-tempo number that highlights that very transparency.

From introspective songs that face the self, to love songs, to numbers brimming with hope, every type of track gains convincing power through Leo’s strength and translucence.

A seasoned actress who commands a dignified presence, able to perform everything from serious roles to comedy, and a singer whose artistry has deepened year by year.
