Rukiryo is an NPC which is located in the Den. By giving this NPC a lightbulb, as well as the respective items for the other members of the Den, a Rukiryaxe will be given to players or an End Times Axe on Halloween 2016. In the Den, he is seen to the right of the table.
Rukiryo, as with all the other Den members, is mentioned in one of the Rukiryaxe Posters, with his saying:
RUMORS ABOUT RUKIRYO
EATS LIGHT BULBS ALSO HAS A THING FOR DUCKS SECRETLY JEALOUS OF GUSMANAK AND HIS DUCKS
This gives the player a hint about part of the recipe for the Rukiryaxe.
The poster can be found on the back of the Wood 'R' Us sign, which is accessed by climbing up a ladder above the second blueprints shelf and climbing onto the blueprint sign. This ladder can be reached by putting a large object, such as a log, plank or even a boxed sawmill or another large shop item, and putting it on the shelf underneath the ladder. You can then climb on top of the object and jump up to the ladder.
In order to find the character in the Den, the player must travel to the Taiga Biome, (making sure to bring Dynamite in order to pass the boulders blocking the entrance) and locate the Hatch which grants the player entrance to the Den. Because the Hatch is covered with snow, the player must find the red eagle. The Den is located somewhat directly under that.
