賀茂 伊澄

A young voice actress of middling popularity who has just made her debut. Her shy and introverted personality is at fault for her lack of acting jobs, however she has another persona as "Ruin", an immensely popular Vtuber.

Isumi is vexed by the gap between Ruin's persona and who she really is.

 Isumi joined the voice acting profession because she liked games and anime, however she learnt quickly as an intern that it is necessary for successful VAs to engage with the public as part of the job description. Having no confidence in her outward appearance, she has turned down multiple requests for public appearances which has adversely impacted her voice acting career.

She took up the Vtuber role of "Ruin" because it was guaranteed that she would not need to face the public. However, the growing popularity of her virtual persona (over a million subscribers) and the lack of recognition plus low pay because of the contract terms with Ruin's agency lead to growing frustration as Isumi has not given up on her dream of being a successful voice actress and has no intention of just anonymously voicing a virtual persona.

After talking to Isumi regarding her lack of popularity, Kiichi proposes to help Isumi out of her current predicament as he correctly assesses she is not capable of breaking out of her current situation alone. Although his proposal is outlandishly reckless, he is successful in getting Isumi out of her contract with help from the Vatican's backers. 

If Isumi is not given up to the ark, her new found confidence and innate talent as a voice actress allow her to rise up the ranks at a phenomenal pace. She gives Kiichi her social contact details and remains grateful to him for helping her pursue her true calling. Rumours of her previous identity as Ruin are also quashed with Kiichi's assistance. /
