Miki believes in selling original works through media franchising in hopes to appeal to markets outside traditional publishing. As such, many of the works he supervised have had manga and anime adaptations.

In the initial draft of Shakugan no Shana, the titular protagonist Shana was in her twenties and resembled Margery Daw, another character in the series, in appearance, however following Miki's suggestions, the character was reworked.

The concept of Oreimo as a slice of life comedy based on otaku culture was planned by Miki based on the style of the author, Tsukasa Fushimi.^[5][6] Kirino Kosaka, the main heroine of the series, was proposed by Miki as like "a gyaru character taken from the works of Tooru Fujisawa."^[7] As a native of Tokushima, he often appears at Machi Asobi which is held in Tokushima City, along with Fushimi.^[7]
