Ah, right. Thank you so much.
One more question. May I ask where did the person who wrote the spoiler get the translation/original?
And moreover, would it be alright if I made minor changes to make the writing more fluid/correct grammatically?
Yes, feel free to edit it.
Original can get from the japanese website. You want the original? RAW or type "魔法科高校の劣等生 raw" at google search. Four short story name in Japan is tenpen, tenpen shotgun, tenpen dekiru and tenpen medatou
Translation they translate by themself.
