I had a friend help me out and he put together this free downloadable High school DxD 2021 calendar.
Plus keeping in mind the limitations of most general printers while debating the epicness of the screenshot and the personality of the character.
As always, you can mix and match to make up your own calendar or you can download a full calendar. The choice is up to you. If you would like to mix and match, you can click and save the below .png images. Or to download the whole calendar, follow the PDF link to a Google Drive file that I uploaded.
