You can ask him to send you a message of confirmation on DeviantArt; or you can ask him to publish that fanart under one of the Creative Common licenses. For example, you can use the following fanart quite freely as it has Creative Commons enabled: http://allukazoldyck.deviantart.com/#/d4kl3zw (look at the License section near the bottom of the right side-bar). Keep in mind that fan-colorings are not fanarts. If you upload fan-colorings, you have to give it a Fair use license, because the copyright holders are still Togashi and Shueisha.
