Ikue Ayu

Ayu is a super famous idol whose name is known across Japan. She’s revered for her cute stage persona and her seemingly humble nature. During her concerts, she never fails to thank her fans, and her enthusiasm is contagious!

...That’s just how it appears, however. Deep down, Ayu is a scheming vixen who regards her fans as mere stepping stones, and values money above all else. She’s so avaricious, she claims to be ‘moneysexual’, and she spurns the advances of men…

At least, she did, until she met Hiroki.
