omoriboy

The OMORI that appears in Omocat's prototypical Tumblr blog Omori Hikikomori, and its short tie in comic Omori's Story. This OMORI is still named similarly to his counterpart in the later appearing videogame, but he's implied to be older than thirteen and seems to be living in an abstracted version of reality unlike the dream world Game OMORI resides in. The name "omoriboy" comes from the URL of the blog, and his actual name seems to be "Hikikomori".

The parody version of omoriboy, created by RainingKetchup and popularized in memes mocking OMORI, also counts under this tag.
