First, I should confirm if these characters exist in a known series. A quick check: Oshikawa Yuri is not a widely recognized character in major anime, so it might be from an obscure or niche visual novel. Tachibana Mary might be linked but also not mainstream. The MVSd583 could be a scene reference or a model number, but without more context, it's hard to say.
