Summary

A tower you can’t leave until you clear it.
All awakened ones entered the tower to become hunters.

The tower is literally like a deserted island.
None of the comforts of the outside world existed there.
Delicious food, alcohol, cigarettes — even the support from guilds or nations was hard to come by.

[Outsider of the Tower]
– You can enter and exit any tower without restrictions.

…But I can?

First things first, I packed some ramen to sell inside.
