A Story of Words and Connection for the Social Media Generation: Popular Children's Author Launches New Series 'Will the Songstress Destroy the World?' on June 17

Poplar Publishing Co., Ltd. will release 'Will the Songstress Destroy the World? #1: The Secret Diva, A Dangerous Live Stream!?' (written by Fumi Yamamoto, illustrated by Mopp Asumi) on June 17 under its children's novel imprint, Poplar Kiminovel.

The highly anticipated new series marks the debut of Fumi Yamamoto, beloved author of the 'Rika's Strange Laboratory' and 'First Love Time Limit' series.

The protagonist, Uta, is a first-year middle school student who secretly performs as a singer under the alias 'Kira'. One day, she finds a mysterious notebook that reads: 'Kira will destroy the world'—and from that moment on, dangerous incidents begin to unfold around her.

This story begins with the shocking phrase 'destroy the world,' but at its core lies the theme of 'the power of words.'

In today’s world, where social media and video streaming are part of daily life, even an offhand comment can lead to misunderstandings, conflict, and emotional harm. Yet words also have the power to encourage others, connect people, and change the future.

Uta is a girl who struggles to speak openly with others. Though she has things she wants to say, she often erases her own words before speaking. But when she sings, she can express her true feelings directly through lyrics.

Her desire to sing, the power of words that move hearts, her budding romance with her protective childhood friend, and the fate of the world shaped by her songs—all come together in this story of courage and love, as the songstress stands up to her destiny by believing in her voice.
