When the two recomposed themselves, Rein noticed a notification on his System.
Level: 122 → 123
[New Skill Acquired] - Liquid Slots: Allows the System to store 2 Springs at once, allowing the wielder to switch between the two at will. (This does NOT allow the user to wield both Springs at once like STO, but it does make it so he can change between them individually.)
(Skill list updated)
To Rein's surprise, the addition of the new skill filled the slot with the most recent other Spring, which was Chloe's Spring. Rein was able to switch to it with ease, allowing him to use it to fill up the hole he caused, burying the dead bodies lying at the bottom.
