A second short story series promoting A Kiss For The Petals – The New Generation! was launched on 12 June 2015. Sisterly Guidance (姉妹のみちびき Shimai no Michibiki) features the students of the main St. Michael campus giving counsel to the students of the annex facility featured in The New Generation. This marks the first proper crossover between the two main series. The translation by Ralen is hosted on this server as a mirror of the original pages.

The first story features Aya asking for advice on her sister Ai’s meddling from Mai and Reo. As of this post, the first of two currently available chapters has been translated.
