Okay, in the most respectful way, this needs a lot of work. It feels like a machine translation.

The following is a sample.

P2 "Uninhabited island, cute junior, swimsuit Nothing can happen..." After the word "swimsuit" either a comma or a period is needed to separate the two parts, and if a comma is used the word "nothing" should not be capitalized.

P3 "What will you do? Senpai" We have another punctuation issue here. The question mark should be moved to after "Senpai" to keep everything as a question, or have a period or ellipses after "Senpai." The second option changes the tone slightly to Mash asking a question, pause, then her trying to get Ritsuka's attention.

Also on P3 "Don't make fun on me Let's go to the sea soon" The problem here is grammar and punctuation. Grammar, it should say "Don't make fun of me." Punctuation, You have either one long sentence that needs a comma after the word "me" and a period after "soon," or two smaller sentences that need two periods instead.

I'm not even going to bother commenting on the quality of the... translation.

Adding to spartan10000's count

rough grammar

every page: what are periods and commas
p.2 today's Mash become more masculine => the entire sentence is nonsensical, but "has become"
p.5 Life guidance to the master => this sentence is incomplete and makes no sense, even in context. There's a verb that should be here that isn't. Provide? Give? Who knows!
p.6 Your answer => same idea here. Give me? Answer me?
p.6 Yeah! My son honestly! => this is complete gibberish
p.8 I better rid master's tons of milk => get rid of
p.9 if you sucked it => suck it. ongoing action
p.9 so many => so much
p.11 super body is about to explode my cock => blow up? make my cock explode?
p.12 my morals going to be disturbed => ignoring how nonsensical this sounds, "my morals ARE going to [...]"
p.12 it's always been disturbed => they've. still referring to morals here.
