Boki Rock got a new illustration of Goto Hitori (Bochi) and Ikuyo Kita for episode 9 by Yui Hara, known as the author of Kin-iro mosaic series that was serialized in Hobunsha’s monthly magazine Manga Time Kirara Max. The official Twitter account posted supporting illustrations drawn by different artists for each episode and released an illustration by YuriYuri author Namori last week. The anime airs every Saturday.
The newly released artwork features Goto Hitori and Ikuyo Kita in maid costumes. Both are holding pieces of cake decorated with a guitar and musical notes and the name of the series, which stands for BTR Boki Rock, can be seen on a star-shaped plaque. The pale looking Boki is fed by Ikuyo with a happy expression on her face.
