I was surprised to see such a large collection in Kousaki Rui's Comiket 78 release Tokimeki Mono when he had just released a sizable amount of illustrations for C77 with his GLASS HEART 5 publication. But I guess it helped that several of the illustrations in the last one were reprints. Some of the ones in Tokimeki Mono are as well, but since they were done outside of Kousaki's doujinshi circle, they're new to me ^^
