What would you do if you had a drop-dead gorgeous Mom? Not only that... but one that's extremely overprotective, extremely kind, and gets lonely extremely easily?

The curtain boldly opens on the ultimate and extraordinary "mother-son" fantasy of Ryuuji, the young man who dreams of being an adventurer, and his overprotective mother, the demonic dragon Karma Abyss!!
