One of my biggest regret in my manga reading life is that I never have the chance to see Tatsugarde becoming canon. And Aoi was grateful of that. Has Oga had any intention of responding to her feeling, he would have showed. Gosh, lately I feel like I have been so deprived of TatsuGarde feels and then I had a dream bout them. So I finally got around to finishing the side stories of Beelzebub and lol, let me talk about the romance bit of it for a sec.

Light snoring could be heard from a small baby currently using his so called father's left forearm as a pillow. Said father currently had his back to his bed facing the top of the ceiling. He had a pair of lazy eyes stare at the ceiling tiles in front of him. Oga Tatsumi was currently wondering why he could feel far more weight on him than usual. He stared over to his right side and saw a big lump of someone else laying on him. The sprawled blond hair over his torso deduced many of his guesses.
Hilda is an extremely beautiful young woman with glossy blonde hair that covers one side of her face and is usually tied in a bun, forest green eyes and has a large bust on par, if not larger than her sister. Her clothes are mostly elegant and black with frills and white quillings, thus resembling elegant gothic lolita fashion. She is seen wearing other outfits on a few occasions. One occasion being right after she wakes up, where she was wearing a modest pink nightgown with her hair down. In one chapter, she was shown wearing a yukata while playing with fireworks along with Lamia.
