It's an Expansion of Character Slots !!I hit the maximum as well~The number of students has reached its maximum...You can't let go of any characters, am I right!!If that's the case, then it's best to go with an expansion of student slots with this shop here ↓ !!It consumes 10 tank souls each time, but you won't have to lose your favorite characters.See post #4602481 for a primer about tank souls.Here!!Here!!With this, we can increase the number of Bokos we have again, Arisu-chan.No no no,
you're supposed to use Bokos to strengthen your skills!!Eh......
We can't do that, can we?... I get it, go ahead and increase your character slots then~Whoah, this is nice!!
