My Favorite Comic My Favorite Comic

The sentence is correct, but generally people use "manga" even in English when talking about Japanese comics.

My most favorite comic is Detective Conan. My favorite comic is Detective Conan.

I have to disagree with the other correctors. "Most favourite" is an unnecessary repetition, and can sound like childrens' speech.

When I was a 1st grade school student, its animer, its anime (adaption) started airing. When I was a 1st grader, its anime (adaption) started airing.

When I was ain 1st grade school student, its anime adaptation started airing. When I was in 1st grade, its anime adaptation started airing.

When I was a 1st grade primary school student, its anime started airing. When I was a 1st grade primary school student, its anime started airing.

Or better phrasing, "When I was in first grade". In the West, I think normally the grades go from 1-12 across primary and secondary school (and middle school, if you're American). So if you say "1st grade/grade 1", people will already know you mean primary school. Note, if you learn American English, they usually say "elementary school".

"Broadcast" by itself is grammatically correct, but it sounded a bit weird to me, so I added the word "being".

"The magazine in which 'Conan' is published" is also correct, but my edit is the more common way people talk.

Unfortunately, many voice actors in Conan have passed away. Unfortunately, many voice actors in Conan have passed away.

Unfortunately, many voice actors in Conan have already passed away. Unfortunately, many voice actors in Conan have already passed away.

Your original sentence is correct and completely understandable, but "have" or "have already" includes the nuance of the cast members passing away over time (rather than, say, due to a singular terrible incident).

Unfortunately, many voice actors in Conanof the original voice actors from 'Conan' have already passed away. Unfortunately, many of the original voice actors from 'Conan' have already passed away.

Adding some words to make the meaning clearer.

The author and many of its voice actors are over 60 years old. The author and many of its voice actors are over 60 years old.

The author and many voice actors are over 60 years old. The author and many voice actors are over 60 years old.

I originally corrected this to include "of its," as the previous commenter did, since it specifies that the voice actors are those involved in the Conan anime. However, I think it's obvious from the context, and I could see other native English speakers phrasing it this way.
