You KNOW the ghost is training her at night, just like THAT doujinshi

@zephyroths probably because miko means shrine maiden and keikaku means plan. So naming the girl who attracts spirits and becomes their vessel (kami/youkai) as such is only fitting, as the job description becomes both their name and nature. (as for miko (yotsuya) mieruko-chan, its fitting because she is essentially what english calls a medium, and later also Spoiler tag im too lazy to make a real tag, but you know why. end spoiler tag)
