The battle ended, and the Daimidaler Type-6 returned to its normal form and landed on the ground where Kazuo, Professors Three, and the commander of the army were waiting.
When they arrived, they could tell that Kazuo and the commander of the army were bickering with each other, arguing with each other that a perverted thing was necessary, and told the government and the army to not be so hypocritical since a human was being made by doing perverted action.
Haru ignored them and came out from the cockpit while supporting the bodies of Kyouko and Kiriko who were very weak at that moment.
Kyouko and Kiriko had worked hard to support Haru to defeat the Super Sound, but in exchange for that action, both of them had this blush on their faces, satisfied expression, and some drool on the corner of their mouths.
"Hey, congratulations on defeating that guy!"
Ritz also came by controlling her robot nearby.
"Thank you for your help," Haru said without hesitation.
Ritz smiled brightly and said, "No problem!" Then she noticed both Kyouko and Kiriko which made her couldn't help but ask, "So what happens to both of them?"
Moriko, Soriko, and Sewashiko also stared at Haru when Ritz asked this question.
Kiriko and Kyouko became even more flustered and snuggled into Haru's chest since they were too ashamed to say the thing which happened on the cockpit of the Daimidaler Type-6.
"Nothing. They're a bit tired," Haru said with a harmless smile.
Yes, Kiriko and Kyouko felt a bit tired and it shouldn't be too bad to sleep at Haru's house after this matter was completed.
It was at this moment a sudden group of penguins appeared from the floating penguin shape of aircraft.
Kazuo and the commander of the army who bickered with each other stopped and the commander quickly ran when he saw the group of Penguins, but Kazuo stared at the Penguins angrily.
"The Penguin Emperor, you bastard!"
"Calm down, Matayoshi Kazuo," the Penguin Emperor said. "As a courtesy, we only stopped by before we returned to our world, and I've something to tell all of you."
"Huh?"
Everyone was wondering what the Penguin Emperor wanted to say and some of them didn't want to listen, but the Penguin Emperor then started to explain to everyone about the origin of the Penguin along with their purpose in this world. However, since their purpose had been gained and they also felt this place was quite dangerous to them, they had decided to return to their own world.
"Ritz will come with the Penguin!" Ritz said with a smile.
The Penguin Emperor smiled and patted Ritz's head since he had agreed to bring Ritz with them. He looked at everyone again and said, "Goodbye, human!"
However, even if the Penguin Emperor said goodbye, it didn't mean that they were going to go away right away since they still wanted to talk to each other for a while, especially since the Penguins were a bit curious about their relationship with Haru, Kiriko, and Kyouko.
"Haru, why do you have two girls at your hands?"
"What's the relationship between the three of you, de gozaru?"
"Don't tell me...?"
"Wait, Dennis! That conclusion is too early!"
"Yeah! Let us hear what the answer is from his own mouth!"
Then the Penguins stared at Haru, Kyouko, and Kiriko at the same time.
Kiriko and Kyouko became shy and hid on Haru's chest.
"Well, both of them are my girlfriends," Haru said.
"......."
"WHAAAATTTTT?!"
Those words were like a bomb to the ears of the Penguins. They wouldn't expect to see a harem in real life which made them dumbfounded.
"Oh, my... harem protagonist!" Ritz was also stunned.
Penguin Emperor nodded and understood why the Penguin Emperor had lost against Kasugano Haruka.
Kazuo didn't think too much since he didn't think that it was bad for Haru to have two girls at the same time.
"Haru! Haru! Haru!" Dennis suddenly called out Haru's name.
"What's wrong, Dennis?" Haru asked. Even though the Penguins' features were similar to each other, their voices and personalities were quite different.
Well, their beaks and front-tail were also a bit different from each other too.
Besides that, they resembled each other and it was hard to distinguish them. Unless they wore clothes similar to the Penguin Emperor.
"Let me hold your hands! I want to hold hands with the harem protagonist!" Dennis said with a respectful tone.
"Ah, how unfair! Me too!"
"Me too!"
The Penguins suddenly gathered around Haru and wanted to have a handshake with Haru when they knew that this guy was a real-life harem protagonist.
Haru frowned but sighed since it might be his last time seeing those idiotic, perverted, and slightly loveable Penguins so he accepted their request.
After they had finished, they also took a picture together.
"Farewell, Kasugano Haruka."
"Well, you can come anytime. I'll treat you to a porn magazine."
"OOOOOOOOHHHHH!!!!"
Everyone was excited when they heard Haru's words.
Kiriko and Kyouko didn't join the conversation between Haru and the Penguins since they talked with Ritz.
"Ritz, be well."
"Take care, Ritz."
Kiriko and Kyouko said goodbye to Ritz since Ritz would join the Penguins to go to the original world of the Penguins.
"Goodbye, Kiriko, Kyouko." Ritz smiled and said, "The three of you should take care of each other, alright?"
Kazuo and the Penguin Emperor talked to each other and it seemed that they had become friends since both of them agreed that lust was necessary for humans and the world!
After all of that, it was time for the Penguins to go back to their original world.
"Humans, do not forget."
The Penguin Emperor gave them a kind reminder before he returned to his original world.
"If you lose your HI-ERO particles, in other words, your libido, you will become Penguins like us. And someday, you will suffer the same fate. Treasure it well."
"I won't say goodbye."
Waving her hand, Ritz disappeared along with the Penguins using the Penguin Device to return to their original world.
Looking at the Penguins, Haru smiled since he really felt that his stay in this world was quite fun, and it was very memorable. He also got three cute girls at the same time which made him feel quite reluctant to go back too early.
However, he knew that since he had completed his quests, he would need to return to his original world in three days.
Haru hadn't told his girls and everyone about this matter, but he knew that he needed to tell them about this matter. When he was thinking about how to explain this matter, he decided to open his reward first.
It might be a bit hasty, but well, he was quite curious what kind of reward that he would receive from the quest.
When everyone was watching the sky where the Penguin Device had disappeared, Haru opened his reward and felt a bit surprised with what he received.
[Ding! Congratulations, you have received a "Stand" ability "Heaven's Door"]
"Hmm?"
"What's wrong, Haru?" Kiriko asked.
Shaking his head, Haru said, "Nothing. Let's go back."
"Yes!" 2x
Kiriko and Kyouko nodded.
Before they returned, they thought to get Chieko since they were sure that the woman was working at the school at that moment, ignoring the fact there was a huge battle on Tokyo before.
