Many galleries from here are missing content. So I tried to make the most complete Higashi Taishi Pixiv gallery. I apologize if for any reason I missed something.

Other Info:
The artist included stories in his images descriptions, unfortunately many were not saved. Still most of them can be found in danbooru, some were also saved in the Wayback Machine.

Another thing that not many people know, he was part from a circle called "Legendary Hall Ninpuu" where he did some illustrations (/tag/legendary+hall+ninpuu). Their works are still available to buy on Dlsite (RG02919)

Some already being translated to Indonesian here:

保存并翻译过東太子过去的文本，可惜当时的硬盘损坏无法启动，丢在了抽屉里。如果某天打算修复硬盘的话，这些文稿就会重现天日吧
