"What was that?" One of the bathmaids gasped.
"Storage magic. As long as it's in contact with my body, I can store it." Arad replied with a smile on his face, approaching Isdis and touching her shoulder.
ZON! Isdis's upper shirt disappeared in the blink of an eye, "As long as I can overpower the wearer's magic, I can suck it."
Arad's stomach had several limitations. For once, he can't store living things. Not because it's impossible, but because they would die.
To store a living being, Arad has to overpower the creature's innate magic control. That means a strong enough individual can resist getting sucked into Arad's stomach. For example, he can suck Isdis into his stomach, but can't suck someone like A-rankers.
The stomach doesn't seem to have a space limit as Arad didn't hit that, but it does seem to have a speed limit. It takes time to suck large things or get them out.
