"I'm Little D., the very clever, very helpful, and very cute demon familiar!"
Little D. No. 2 is a tiny demon from the Demon Lord's Castle and was mentioned to have assisted MC with their assigned RAD tasks. He is first introduced in the story in Lesson 7-10 as a guide for the items and their history in the castle.
No. 2 also makes an appearance in the event Welcome to the Bunny Show. The owner of The Fall allowed the Little D to run things at the nightclub in his absence, so No. 2 was in charge of training the demon brothers.
No. 2 is very knowledgeable and likes to give out information when asked. He also likes to tease Mammon by mimicking his thoughts out loud, calling him "Papa", and even scaring him when he and MC went to the haunted house.
In Tasks, he and the other Little D's appear as a battle opponents with the Special Skill "SHADOW ATTACK" spelled in reverse. Their battle dialogues are also spelt in reverse. Little D's can also take the shape of the demon brothers during battle.
- As of now, he's the only Little D. to make an appearance in the main storyline.
- He's very fond of MC, for Diavolo told MC in a chat that he missed them and asked if they would like to visit him.
