It is Ok?

This is good. I was not familiar with うる星やつら so I had to research about it. I don't read very many manga, but I may give this a try.

The big problem with what you wrote is that the first "sentence" is not a proper sentence. (1) There is not verb.  (2) It should be two sentences. In my correction, I split the opening into two sentences, but I did not add a verb. In the note below, I've included some suggestions.

* Missing verb. Your opening sentence means 今日は『うる星やつら』マンガだって多いかわいい図が。It's confusing and doesn't make sense. But if you split it into two parts and add a verb:

"Today, I bought the book "Urusei Yatsura." (今日は『うる星やつら』という本を買いました。) or

"Today I will tell you about the book "Urusei Yatsura." (今日は『うる星やつら』という本についてお話します。) or

"Today I will extol the virtues of "Urusei Yatsura." (今日は、本 の『うる星やつら』の美しさを祝いたいです。)

I hope this helps. Let me know if you have any questions.
