This week, tens of thousands of people on twitter celebrated the 10th anniversary of startthe airing of "Madoka Magica" on the air."

Ten years ago, I was still a high school student and indifferent towards Japanese anime.

MoreoverAlso, I didn't have enough time to watch TV in order to work hard onbecause I was studying for the university entrance exam.

But, even if IIf I had watched just one episode of these popular anime, such aslike "Madoka Magica" and "STEINS; GATE"," I would bprobably would have become addicted to them.

This is Subjunctive II tense since you're hypothesizing about something which could have happened but didn't.

This decade must be a golden age for late night anime, which are broadcasted on TV and targeting for teens and adult audiences.

The phrase "targeting for teens and adult audiences" isn't really necessary.

The movie of lLate night anime had never earned over two billion yen until "Madoka Magica" sat a new recordwas broadcast.

A movie is usually longer than an episode of an anime series.

Last year, twelve moviesanime earned over two billion yen in Japan even though theaters restricted the number of seats for them.

This can also be written like this:

"Last year, twelve anime earned over two billion yen in Japan despite the fact that theaters restricted the number of seats for them."

Two of them are late night anime series.

One is my favorite anime series, "Violet Evergarden," andwhile the another is "Demon Slayer"."

The logic here is unclear. The claim is: If you watch anime, you'll become addicted.

Case I: You have already watched anime and became addicted. In this case, it should be past tense, and you'd know which series it is (so you wouldn't write: such as "Madoka Magica" and "STEINS; GATE").

Case II: You haven't watched anime before. Then how do you even know you'll become addicted?
