Does Marine have any interests beyond her shitty taste in anime, manga and games, drawing and coom shit?
She can't cook and has the palate of a child. So she obviously has no interest in food.
She has horrible fashion sense. So no interest in fashion.
She has poor general knowledge. So no interest in history, science, the arts etc.
No interest in dance or any athletic endeavor.

Her topics of conversation ultimately come down to: her shit taste in media, stories about her colleagues and family, whining about her previous job, pornography and mundane observations about everyday life.
To call her a basic bitch would be an insult to basic bitches.

Her genmates all have a variety of interests and hobbies. Lets face it they only like Marine because she is popular with ironic otakus/weebs.

Oh and she is also a complete bitch.
Remember that survey she did? Everyone was sucking up to her in it but even then they couldn't bring themselves to call her kind.
