As unpopular as DDD itself. A story featuring featuring “Ookumaneko Mokumoku” -until then just a side character- and a well-known little sister: “Ishizue Kanata”. Shunji Enomoto drew a short manga based on its events (pic related).<br /><br />Across the story we can see a Kanata with the urge to kill some time (and other things), making her way out of her chamber (more like a prison) with the help of the docile Origa Vice-president. Then, Kanata resolves going to a room nobody has stepped in for a long time. That room was located in her own ward; “Ward D” and its number was: “The Room No.404″, however, as this room was a mystery to even those patients (monsters) of Ward D and even though what lied inside resulted very attractive to pry into, no one tried doing it before, after all, the Hospital files didn’t even consider an active room anymore.<br /><br />Before she destroys the iron door intruding in her way, a dim, puzzling voice spoke a few words, resembling a warning to her:<br /><br />“Don’t come in. Don’t come in. You cannot withstand my power. If you come in you’ll regret it.”<br />“Cherish life, don’t enter my world.”<br /><br />…this of course was the voice of Mokumoku, a 30 years old NEET who hid an unimaginable power.
