Comment by Saya Tsukigomori on S-Class Hunter Heals with Monsters - Chapter 38

@Saya Tsukigomori i thought the same thing,  might just be for everyone else that keeps ok coming in and out like the director and cook

@Saya Tsukigomori the gate stone channels and condenses mana in a uniform manner. If he just randomly opened a gate, it would fire up all the sensors in the hunter department that there is a firggin S-Rank Demon Gate.
