These are the sources of the pictures I used to make the background:

 

• Block Note picture 1

• Line 1
• Line 2

 

The main graphic of the site is made with a screenshot I did from the anime ending, and the other pictures are from my favorite panels of the manga. Also, the GIF I made for the statistics of the site is from the preview of the second episode, and the chibi I used for the footer is from a gadget.
