After Casey finished helping out her daughter with killing the rest of the train of monsters that she accidentally made, Ethan picked up the loot (that only he could see) and put it into his deep pockets.
'When you said that my system was different from others, I expected to get infinite pocket space. Or at least an [Inventory], but nope. I have to carry everything by hand/in my pockets! I'm kind of disappointed.'
[You won't have to worry about that soon. As long as you level up, you will receive an [Inventory]. You are getting close to unlocking it.]
'Really? When will I get it?'
[It's at or around level 20. Not going to tell you for sure though. I can't really tell when you're going to get it either. All I know is that the more proficient you are with your [Abilities], the more you will gain from the [System].]
'Thank you for the information.'
[You're welcome.]
