Hi guys! I just wanna share my fave site where you can download the manga volumes in bulk per volumes. You can finally read  Aoharu X Kikanjuu Manga even if you don't have internet connection in JPEG format.

Tips: 

*Make sure you are registered in the site so you are allowed to download from their website.

*It't just one click away directly from the link and there's no pop up window so its easy to keep track of your downloads directly with your browser.

*The manga that you downloaded is in WinRar so make sure you extract it for you to be able to see the contents in JPEG format.
