The virtual world of OZ has taken Japan by storm. Constructing an avatar in this real-world simulation grants users access to a wide range of features—from playing games to processing legal documents. Due to its overall convenience, OZ's popularity has skyrocketed since its inception and has been deemed the world's greatest communication tool.

Introverted OZ moderator Kenji Koiso had decided to devote his summer vacation to overseeing the system's maintenance. However, he changes his mind after being invited to accompany fellow student Natsuki Shinohara to her family's residence, where the Jinnouchi clan is gathering for the impending 90th birthday celebration of her great-grandmother.

Upon their arrival, Natsuki introduces Kenji as her fiancé, which comes as a shock to both himself and her great-grandmother. While struggling to keep up with the actions of his crush, he receives an anonymous text. Enticed by the complexity of its encryption, he decodes the message and sends a response—unknowingly bringing about a great catastrophe for OZ that will have dire consequences.

Please, go read something else.

For those of you who are left, you will find an enjoyable, short story. There is a nice little romance here and an absurd plot about AI. But the core of this manga, the reason to read more

This is the first manga that I have felt compelled to write a review of. Some minor spoilers to follow.

First of all, a warning to everyone, the description that MAL provides is very misleading. The so called "parallel dimension" is actually a computer world.

The art is decent, I had no complaints about it, though it wasn't spectacular.

The characters however, really ruined it for me. To be quite frank, they were stupid and unbelievable. There was a lack of communication between all members of Natsuki's family, leading to the collapse of a huge computer server and thus eminent nuclear war, because one family member took read more
