XI summary:
This manga contains a series of one-shots that feature Hanai Shishimaru, the perverted boss of ‘The Help-for-Help-Seekers Room’, which will do anything for their clients except murder. Causing divorces, turning someone gay, ‘relieving stress’ on a crowded train…… Just how far will he go? The first, fourth and fifth one-shots, XI -Extreme Love-, Fool and Shadow Game, as well as the extra, La décadanse, are sequels to Buddy System.
