Time travel is not to fight and kill, but to be human.
In the morning, go downstairs to Ju, and then take Fairy Ib to the upside down mountain to see the scenery;
At noon, I went to Yuanyue, and then went to listen to Muse's concert with Erina;
Camping by the river at night, leaning in the arms of the wind speed dog and watching the magic girls fight each other.

Those who say that they are dark souls in the morning, war hammers at noon, and those who are sheltered at night are all forked in Siberia to dig potatoes!

Neos: A demon, what else can it be?

Dumbledore: Huh?

———

Snape: You must stop using the power of the demon!

Neos: But... we... are wizards...
