So netmarble says it might bring back KoF units again in the future. I wanted to know if someone remember seeing the same info in slime or aot banner before or they just thought about making it possible from now (since KoF event i mean).

Asking because i don't see slime event units forshadowed in the inventory so i deemed they'll never come back. It's a slight hope and i m sure it'll take a long while for them to recycle these units but who knows
