Fifteen years later

Y/n grew up to be a strong fighter. During his school days he was a member of the boxing club, one of the best. Nero was anxious about Y/n's powers, but they didn't show, even though he was an adult now. He taught Y/n to fight with a sword, how to shoot and use different kinds of other weapons. Due to the lack of demonic powers, he had to count on his physical strength and dexterity. Nero and Nico took him for hunting a lot, though Kyrie didn't like putting her son in danger. She understood that need to fight though. Y/n always looked up to Nero.

-What the hell is this? – said Y/n as the trio was walking through the city.

-A hell gate? – said Nero, trying to answer, but the shock in his voice made it sound like a question. Last time he saw it was around twenty years ago. – How's that possible?

-And who the hell wanted to be a king of hell again? – yelled Nico in frustration.

In that moment a bunch of demons jumped on them. Y/n and Nero got rid of them easily. They ran to the van as fast as they could. Nico rolled over some demons while driving in the direction of the gate. Once they reached the monument with a huge hole in the middle of it, Nero jumped out of the van. Y/n wanted to follow him, but Nero stopped him from getting out. In that moment two demons jumped out of the gate. One of them was oddly familiar.

-Dante?! – Nero's eyes almost went out of the sockets when the demons turned into the human forms. – Father? How are you both still alive? Damn it, you didn't even age much.

-Well. – said Dante. – Time passes differently in hell. You grew up.

-What the hell do you mean I grew up?! – yelled Nero as Vergil rubbed his temples. – I was grown up all along!

-Who the hell are they? – asked Y/n, getting out of the van. Vergil and Dante looked at him surprised. Y/n walked up to his father with Agni and Rudra in his hands, ready to kill.

-Are those toys mine? – asked Dante pointing at the weapons.

-Yeah, I had to equip him with something before he started hunting demons. – answered Nero, putting his hand on Y/n's shoulder. – The guy in blue coat is your grandfather, while that idiot in red is his brother. Dante, father, meet Y/n Vergil Sparda. My son.

Dante and Vergil looked at their youngest relative, who was staring back at them with fierce look in his eyes. Dante started laughing, while Vergil acted more composed. He walked up to him and extended his hand to shake.

-Nice to meet you. – he said. Y/n shook his hand back firmly.

-Likewise. – answered Y/n.- So I'm named after you huh?

-It seems so. – answered Vergil. He would never admit that, but he felt a touch ow warmness in his chest when he got to know that his grandson had his name.

Dante shook Y/n's hand as well, but in a completely different manner. He did it chuckling, then he patted his shoulder.

-Name's Dante. – he said. – I'd love to be called uncle.

-You haven't changed at all. – Nero shook his head at Dante's behavior and went back to the van. – Come on, we have to talk about that hell gate.

Y/n followed his father huffing. Dante jumped in the van as well with Vergil right behind him. Dante was surprised with his brother's behavior, but didn't question it. He felt the strange vibe coming off from Y/n when he was standing close to the gate. Nero sat down at the table, while Y/n stretched on the couch.

-So, what's about the damn gate? – asked Nero after the squeal fit from Nico.

-Our old acquaintance came back. – sighed Dante. – I'm sure you've heard about Mundus.

-Isn't he the one who fought with Sparda? And you? – asked Y/n.

-You know the story, nice. – grinned Dante. – Yeah, that's exactly the same bastard. And he's back. This time we have to kill him, not just kick his ass.

-So in other words, you screwed up. – said Y/n smirking. Vergil chuckled at Y/n's teasing, making Dante irritated.

-What the hell are you laughing at? – growled Dante. – You got your ass kicked, then became his marionette on the Mallet Island. I kicked your ass three times!

-And you got your ass kicked when I was a king of hell! – argued Vergil. Y/n just rubbed his temples, feeling the rage raising.

-Shut the hell up both of you! – he yelled over them. – Now tell me how to get rid of Mundus for good.

-You're not fighting him. – argued Nero. – It's too dangerous.

-I'll become dangerous if the yelling will continue. – said Y/n and ran his hand through his hair. – Now talk.
