Let the experiment begin 2: Heroes reunited

Momentum Break

Everyone was back in the world of Highschool DxD and were relaxing Akira was at home as he then heard the sound of the door open to find Sento and Rossweisse both happy and Akira noticed a wedding ring on Rossweisse's ring finger

Akira: "Wait a minute...don't tell me."

Sento: "Yes son I've decided to settle down and ask for her hand in marriage."

Akira: He looks at Rossweisse "...So how did it happen?"

Rossweisse: "Well..."

Flashback

This was three days ago as Sento and Rossweisse were on a date usual as the two were talking about stuff.

Sento: "So how was work?"

Rossweisse: "Oh you know it was good. The students are really nice."

Sento: "Well I hope my son actually said hi to you."

Rossweisse: "Wait you had a son?"

Sento: "Yes. He's about 5 feet and 5 inches, black hair, blue eyes, has some similar traits from me." And that was when she started having flashback from Kyoto

Rossweisse: "Oh I think i've actually saw him before wasn't his name...Akira?"

Sento: "Yep he really has more of what I would have done. Creating stuff."

Rossweisse: "Interesting. Does he have any hobbies?"

Sento: "Fighting antagonist."

Rossweisse: "...What?"

Sento: "Yep."

Rossweisse: "Wait when you mean antagonist do you mean..?"

Sento: "Yep he and his friends help fighting those who try to destroy this world."

Rossweisse: "Huh now that you mention it there was news of how there were people in these weird armor, one of them looks have more of a rabbit."

Sento: "Well if you want just ask him i'm sure he'll want to show you."

Rossweisse: "Ok. But I have a question why did you wanted to go on a date with me?"

Sento: "Well this date was something I actually wanted to ask you something important." Then he got up and got on his knee and pulled out a box "This question is: Will you marry me?" She gasp and tries not to cry and then she went to hug him

Rossweisse: "Yes!"

End of flashback

Akira: "Well then now I am caught up with the last three days."

Sento:  "What were you doing for the past three days?"

Akira: "...travel through another world like Decade."

Sento: "...I'm proud of you."

Rossweisse: "Wait isn't that dangerous?!"

Akira: "No unless you don't have magic, hand to hand combat training, sword training, or a driver to become a Kamen Rider." Then he shows the build driver

Rossweisse: "So you're a Kamen Rider?"

Akira: "You would be surprised that there are about other students in the school that are also Kamen Rider."

Rossweisse: "I'm so lost and so confused. Approximately how many?"

Akira: "6 including me."

Sento: "Plus formally 3 including me."
