Kuina gritted her teeth and swallowed the entire Devil Fruit, as if it were Mousse's head.
But Kuina's expression immediately changed dramatically. "Why are my feet sinking into the ground? No, why did I become so heavy?"
Hearing her startled cry, Mousse merely smiled and remained calm. He had already read the Devil Fruit Encyclopedia's detailed descriptions, after all; unlike before his transmigration, when he had known only their limited displayed effects.
Mousse had always felt that the two Devil Fruit abilities capable of altering one's own weight had been developed terribly, and that both users were ridiculously stupid. What the hell was with doing nothing but flying up, increasing their weight, and dropping down to smash people? Were they specifically there for comedy?
Only after seeing the Paramecia Devil Fruit Encyclopedia at home did Mousse understand that these two Devil Fruit abilities altered the user's mass rather than their weight.
That meant that after increasing their mass, their bodily inertia increased proportionally as well, making their movements extremely clumsy. Flying up first, then increasing their mass and dropping down to crush someone was at least somewhat feasible in practice.
But after figuring out scientific training methods, Mousse realized that these two Devil Fruit abilities could actually serve as portable Gravity Rooms to aid training. Even without Seastone, one could maintain maximum training efficiency at all times.
That alone made them highly suitable for Kuina, whose physical talent was lacking. Added to that, the ability could enhance the power of her sword slashes, and unlike many other Devil Fruit abilities, it would not obviously change her fighting style and lead her away from swordsmanship. It was clearly an ideal fit for a girl determined to walk the path of the swordsman.
"And it even comes with flight~" As Mousse thought
