Boys will be umm... boys. And sometimes, stories are written about what happens when a group of good-looking boys get... close. Although this particular genre of Shinsengumi stories is more often told in fan-made doujinshi, there are a few we have to feature:
Bakumatsu Seishun Hanafubuki
Two volumes, by Kamo Nabako, published by Japan by Biblos (BExBOY Comics). Mostly lighthearted yaoi stories, featuring Hijikata Toshizo x Okita Souji, but there’s other pairings as well. Unlicensed outside of Japan, and out-of-print, but not hard to find.
Volume 1 ISBN 4882718936
Volume 2 ISBN 4835210107
Shoshite Haru no Tsuki
Five volumes, by Ikushima Miya, published in Japan by Houbunsha. The main pairing is Hijikata x Okita, but the stories eventually give all of the major players their own relationships. Unlicensed outside of Japan, and out-of-print, but not hard to find. Please visit our downloads section for the first four volumes, translated long ago by Hana-mi.net.
