This "Tribute to Aizawa's Birthday" doujinshi came from Takeo from Pixiv and translated in English by me. This doujinshi has two parts. The first part posted here in Izuocha (Book 3) while the second part will be post in Todomomo (Book 1). Since nobody translated these 2 doujinshis, PLEASE DON'T SHARE OR REPOST THESE DOUJINSHI TO OTHER SITES.
