By now, Fang Zheng had more or less figured out what was going on.
Clearly, the Magical Girls in this "reverse world" lived by a cruel set of rules. The creature called QB granted their wishes, then had them make contracts and become Magical Girls. However...
"They're just little girls. Anyone can tell this sort of thing is definitely going to end badly."
Fang Zheng shook his head helplessly and sighed.
"Huh? Teacher, how do you know?"
Hearing Fang Zheng's remark, Sakura asked curiously. Fang Zheng merely shrugged.
"Although I don't have any fondness for that thing called QB, I admit it said one thing that was right: equivalent exchange. It helped those girls fulfill their wishes, so naturally those girls had to accept the result of that exchange. But little girls are still little girls. Anyone even slightly more mature would think very carefully before accepting an offer to grant any wish."
"Why, Teacher?"
Tomoyo also voiced her question curiously.
"It's very simple."
Fang Zheng sighed.
"You may not know this, but in other worlds, granting wishes isn't difficult. For example, in my world, mages and sorcerers can learn spells called the 'Limited Wish Spell' and the 'Prayer Spell.' In Little Black and Illya's world, there is also the 'Holy Grail,' which can grant any wish."
"Huh? Something like that exists?!"
The girls were all stunned. Even Akemi Homura, who had been standing silently nearby, gave him a surprised look.
"But do you really think that's a good thing?"
Little Black sneered as she spoke.
"In fact, anyone who pursues that kind of result will ultimately meet a miserable end."
"Why?"
"It's simple."
Fang Zheng snapped his fingers.
"Because when you made the wish, you only thought about the result and never considered the process."
"...What does that mean?"
