Original character by [[Rakurakutei Ramen]] in the Karin-dou series.

He goes to the same school as [[ujikintoki_tamaryu|Tamaryu]] and the other youkai school crowd, vaguely making him part of that cast.  However, he is mostly defined by being the love interest of [[Shiraishi Sara]]. He almost never appears outside of her presence, and usually only while being glomped on by her. 

Because of this, he frequently is only referenced as "My Darling!"

Kiyoshi is a frog-youkai, which is favored prey of the sort of serpent-youkai Sara is, making her affections more than slightly uncomfortable.  

He also has the distinction of being one of the very few named male characters in the series, even if he never takes an active role in much.
