I couldn't find an English version so I put the fan translation of the sketch on top of the Dungeon Meshi: Adventurers Bible Complete Edition pages of this comic
The official Toei Tokusatsu Fan Club website has a brand new webcomic spinoff of Ohsama Sentai Kingohger called King of Gokkan: Ohsama Sentai King-Ohger.
Thanks to @martosi231234 for pointing this one out to me!
The manga focuses on Rita, which makes me extremely happy!
