Well, not all four of them are 2 years older (the exception is Yuzu who is a 2nd-year) but we'll find out in future episodes how one gets into S4.

And yea, already the setup is looking like by this time next year we may be looking at Yume and Laura being in S4. It'll be interesting then to see how Koharu grows if she somehow also makes it into S4.
