The Time Gate was never designed with other universes in mind, but when the Sailor Cosm began to be targeted by other universes, it became an unintended barrier, positioned metaphysically so that all the bridges and dimthreads trying to reach the Senshi Cosm would first have to punch through the pocket of reality the gate occupied.
As a result, the Sailor Pluto who guarded the gate had found herself the first targeted by anyone who wanted to invade her home universe. In the end, ETCHI's arrival and subsequent conquest are a testament to her failure and the ultimate obliteration of the time gate itself.
As the ETCHI membership began talking about Sailor Pluto, in a fashion design firm the intern Setsuna Meio paused feeling that someone was talking about her. But in point she was only partially correct because the Sailor Pluto who had guarded the Time Gate was her previous self from the Silver Millenium, coexisting with her now because of the remnants of Time Travel.
