S3·E7 Liar

A new boy named Inuo Atsushi has transferred to Yuzuki's school. He claims that he moved from Tokyo because his mom is ill, but in truth, his dad left his mother and, ashamed, the two left Tokyo. Due to the stress of lying and taking care of his ungrateful mother, Inuo frequently visits the Hell Correspondence website, never typing in a name. However, after he reveals the secret to his classmate Washizu and is beaten by his mother for doing so, he types in Washizu's name. Out of good faith, Washizu spreads news about Inuo's real situation and tries to motivate him to seek help. However, for continually meddling with his family business, Inuo sends Washizu to Hell. Afterward, he becomes insane.
