Debo Yanasanta are a set of quintuplet Debo Monster brothers (with numbers on their heads to tell them apart) who are themed after Christmas and armed with Christmas tree-like swords, able to merge with each other to increase their strength. Their attacks are the Merry Chrismash with a sword and the Candle Beam from the candles on both shoulders.
Debo Yanasanta are voiced by Chō who previously voiced Shitari of the Bones from 2009 TV series called Samurai Sentai Shinkenger and later voiced the Hammer Shadow from 2014 TV series called Ressha Sentai ToQger and Yokai Ungaikyo from 2015 TV series called Shuriken Sentai Ninninger.
The Debo Yanasantas are created to serve to Dogold to distribute poor gifts containing Deboss' Super-Growth Cells that absorb children's aggravation to merge into numbers of Clone Deboss that Dogold siphons the emotion from.
The first and second Debo Yanasantas enact Dogold's scheme to capture Kyoryu Red by combining into a form with twelve times their normal strength. However, the two are destroyed by Kyoryu Red and Kyoryu Gold with Dogold deciding to summon their remaining brothers to Japan to enact a new plan to capture Dantetsu.
The trio having merged into a form with 345 times greater strength, Debo Yanasanta eventually betrays Dogold for his true master, Endolf. Enlarged by Endolf, Debo Yanasanta is quickly destroyed by Gigant Kyoryuzin, Pteraiden-Oh Ankydon, and Plezu-Oh Bunpachy.
