Exhentai is a locked version of E-hentai's gallery which has something need to be hidden, if you want to access it aka get pass sadpanda, you need at least an E-hentai's forum account, I will show you how to get into it without touching the panda.
First, you need an account like I said, follow the link bellow to create one.
Then, clear cache of the browser, if you touched the panda before, the site will save a cache that direct you to the panda and won't allow you to login, you also can try Incognito if you don't want to delete your cache.
Last, login to the normal E-hentai's gallery with the link bellow, or just simply click to My Home on the direct tab of it
Now you can go to Exhentai and see you can access it normally once you logged in. The key to get pass sadpanda is not touching it! Have fun browsing there.
Note: It can takes some time since resign to be able to access Exhentai. As far as I know, admins of E-hentai has to operate it manually, you can actually join the forum and active around for a faster confirmation.
