Little D. No. 2

"'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.

He later returns in Lesson 25-10 when he was separated from Diavolo and Lucifer and runs into Mammon and MC, heading for the traveling carnival to look for them together.

In the event Wedding Vows, No. 2 acts as a photographer, visiting the House of Lamentation to look for a model for a wedding magazine.

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.

Personality
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 (Lesson 25).
