Once the two successfully transferred to hell, Sebastian led Rin to the room where the party was in full succession. Demons were in a cluster around the young Baby beel and his human 'father'

No one paid any attention to the arrival of Sebastian and Rin.

Rin scratched his head and was looking around. "So, this is a demon party?"

"What were you expecting, Master Rin?"

"I dunno, something cooler?"

Sebastian spotted a familiar face and wandered over to the said demon, leaving behind Rin.

"Hello Hilda,"

The demon Hilda lifted her cup to her lips and was about to take a sip, however at Sebastian's words, she lowered the cup.

"It's you," She growled, eyes narrowing.

Sebastian smiled, "I go by Sebastian Michaelis now,"

"Well Sebastian, you best stay away from the young Master Baby beel or I'll kill you," Hilda growled, her hand hovering above her umbrella.

"Baby beel is related to my master. I can't guarantee that I will stay away," Sebastian responded, glancing at Baby beel and his human father.

"You're just as disgusting as ever," Hilda said.

Sebastian put on a hurt expression. "Such cruelty. I am thoroughly offended,"

Hilda glared at Sebastian silently.

Sebastian replaced his look of hurt with a smirk.

"The fate of the Beelzebub faction is in good hands," He said in a mocking tone, glancing back towards Baby beel and his human father.

"Don't you dare speak that way about Lord Beelzebub! He will be the one to bring the pathetic humans to their knees!" Hilda yelled angrily.

"So you say," Sebastian responded with a shrug.

Hilda was about to retort when Baby beel's human father, Oga Tatsumi approached.

"Oi, Hilda, How long are we gonna be here? Baby beel is getting bored,"

Baby beel was pouting, with his arms crossed.

"Young Master," Hilda cooed tickling The baby's chin.

Sebastian stiffled a laugh when Baby beel simply turned his head in annoyance.

Hilda's face turned red. "S-shut up!" She yelled, glaring at Sebastian.

Sebastian walked over to baby beel and leaned towards him.

"Lord Beelzebub, whose a good boy? You are!" Sebastian said before covering his eyes and then saying, "Where's the good boy? There he is!"

Sebastian removed his hands from his eyes.

Baby beel blinked in surprise for a moment before squealing in happiness and clapping his hands together.

Sebastian pulled out a knife and handed it to baby beel who excitedly waved it around.

"Oi! You shouldn't give baby beel a dangerous thing like that!" Oga protested, attempting to take the knife from the baby.

"Its perfectly fine, a knife wouldn't be the most dangerous thing baby beel has gotten his hands on. Remember, Hilda?" Sebastian questioned.

Hilda's face was still red and she looked away without responding.
