Otonashi Meru is student no. 16 of class 2-F. Meru is a quiet girl who can only communicate with others via texting and e-mail. However, the contents of her messages are poisonous. When provoked after being stuck in an area with no cellphone service, she starts babbling in an incredibly dark language (the kind used during demonic possession). It is revealed that Meru stopped talking after being teased about her voice in elementary school. Her family name, Otonashi, means "soundless", while Meru is derived from the Japanese loan word for "mail".



Meru is an extremely shy girl, often finding it super difficult to communicate with people. Her only way of communicating is through text, and it is unknown as to what her voice sounds like.

When texting, Meru is a completely different person; abusive through her texts as if it's a normal thing for her. This upsets Nozomu as he seems to have people bullying him over the internet.

Her phone is an extremely important item to her; which was shown in her debut chapter, that when she loses her phone (or in this case, loses service range), she becomes some kind of demon, speaking in a undecodable language, which has been described as being "echoes from hell", which has the possible ability of forcing people to go insane. This demon was sent back to hell once Kafuka exorcised it with a cross. In reality, Meru may simply just fluster.
