キラ天使ちゃん

One of the angels born from Nene's mind. Despite it's imaginary nature, it's visible to some people. The angel is unable to communicate verbally, so it relies on summoning horror-like letters to guide it's target. It finds itself busy not only with doing it's master's bidding, but also with taking care of Nene's mental health. That's just how it goes in an angel's weirdly wonderful workplace.
