In ours land is any website about Usagi Yojimbo in Polish. And I think that is no good

I guess that this sentence necesaary (of course in polish) on website is:
But have I anything else make? Need I assent from Stan Sakai?Usagi Yojimbo, including all prominent characters featured in the stories and the distinctive likenesses thereof are trademarks of Stan Sakai and Usagi Studios. Usagi Yojimbo is a registered trademark of Stan Sakai. Names, characters, places, and incidents featured in this publication either are the product of the authors imagination or are used fictitiously. Any resemblance to actual persons (living or dead), events, institutions, or locales, without satiric content, is coincidental.
I will be thankfull for your help...
