As a titan, Cabela is undoubtedly unique.

A unique body that can shrink and transform into a humanoid form

Unique timidity

When Godzilla and Ghidorah fought and destroyed her home

She: Waving her hands in protest! The two bosses probably didn't see it, so run away! Find another place to settle down

Until she learned magic (her smile gradually widened) My fellow humans, it makes sense for me to fight with magic~

As a magic school, Hogwarts certainly never thought that it would admit a monster.

Professor McGonagall: I think it is embarrassing for me to take this new student.

Dumbledore: How could that be? The child is... 20,000 Leagues Under the Sea!

As the companion of a Titan, Hermione said she was shocked that Campbell could be so soft and timid.

Canberra: Just tell me whether you like it or not!

Hermione: I love it!

(The Big Bang Theory×HP. Warning to otome fans, especially those with a special madness ⚠️) Penny suddenly discovered that her bed had become a passage to another world. Every night it was connected to the beds of people from other worlds. There was always a stuffy old man who called himself "Professor" sharing her bed.

This guy had a terrible temper and a sharp tongue, and he always said things to her that she couldn't understand. And then, after an accident, she was able to see him? What's more, she could enter and exit his world?

Snape's perspective: At first he thought it was the Death Eaters who were causing trouble, but later he found out it was a curse and a calamity for him. He was the only one who could sense the damn stupid woman. No matter how many times he changed beds in the room, he could still feel her body approaching like a gorilla when he slept at night, and magic was ineffective on her. Later he could see her, and she was even more shameless to threaten him with this, the woman who only knew how to drink and eat, and blackmailed him with "beauty" magic.

He was a fool with only a pretty face, so he wouldn't fall for her trick. But as time went by, when everyone could see her, Snape always felt like he had lost something...

"Don't put all your hopes in the 'savior', let me carry the burden!" "Believe me, there is nothing to fear from Voldemort, he was never our true enemy!" Ethan Vincent, winner of the 2008 World War II Award
