Ever since the barrier was broken and monsters rose to the surface once more, it seemed like despite the odd reception that they received from the Humans of Ebott, everything was starting to take a turn for the better. But almost a year later, the others couldn't help but notice something different...specifically...SANS was different. The usual laid-back, wise-cracking skeleton was acting...strange.
