How did Warriors end up with idols??? (Male reader x Multiverse, Rider saga)

Lets get started, shall we?

"Heya, Ryuga!" Goku greeted me, "Sorry that I disappeared suddenly at that time."

"Where have you been after I'm badly injured 5-6 years ago?" I asked while getting off the bed.

"I will tell you if the time has come." He replied with a smile.

"What time?"

"Find it out yourself, that's what you always teach Honoka right?" Goku teased with a smug. I blushed with embarrassment, " You want to restart the training with me? There's a lot for you to learn."

"Can Honoka join?" I looked at her explaining that she will be a Kamen rider in the future.

"Understood, okay then, let's meet on Saturdays and Sundays if y'all are free." Goku replied while smiling.

"Oh, by the way, Goku-san," Honoka asked, Goku turned his vision to Honoka, "Why not weekdays?"

"2 reasons, first, I'm a teacher at Hanasakigawa Girl's High School and second, you guys have school right, so it's better if it's on weekends."

"What? Honoka, did you hear it?" Honoka nodded, "Kotori, did you hear it?" Kotori also nodded.

"Why, no, how?" My eyes widen.

"Dragon Balls." He replied straightly.

"Oh," Well, that's the easy answer that I didn't think about it, "That makes sense."

3rd person P.O.V...

Goku looked at the time and with his phone with is a Galaxy A60, it was 9:30 right now and he needs to go back to his working place. He left Ryuga and the girls in the infirmary.

"So...what do we do now?" Ryuga got up from the bed.

"Let's go to our classes right now!" Honoka shouted with joy.

"You are breaking my ears right now with the high pitch soundwave you lob." Veins started to appear on Ryuga's temple while his fake smile is "activated".

"Kotori-chan...Help me..." She hid behind Kotori with fake tears after she knew that he was triggered by the scream of her, Kotori giggled.

"Fine...Let's go to our classes." He sighed with defeat. Before Ryuga walked out the door, he stopped with his left leg and right hand raised, "SHIT, I DON'T KNOW WHICH CLASS AM!"

"I was going to take you there, idiot onii-chan." Honoka pouted.

"Fine, no more chitchats, let go." Ryuga replied before he walked out the door, the girls followed him.

3rd floor...

"We arrived!" They stopped at a classroom which was written 3-B on the sign.

"Third year huh." The only boy in this school looked at the sign.

"Now let's find the director of our school." Kotori suggested, Honoka and Ryuga nodded.

At the director's office...

I knocked on the door of the main entrance of the director's office.

"Come in." Voice came from inside, then we went in immediately, with a "Sorry for the interruption." said from my mouth.

"Ah, Ruyga-kun, you've come as I expected." The director recognized me after I came in.

"It has been a long time, Minami-san." I bowed

"Mum, why did you accepted Ryuga-kun as a student even it's a girl's high school." Kotori asked.

"I accidentally accepted him as a student." Minami-san stuck out her tongue.
