偷偷狠狠的日日

The one who suddenly jumped up and hugged Tenku was a little girl with short hair. She has a cute oval face and looks very adorable. That little girl is Haruna and Tenku\'s younger sister with only one year of age difference. Haruna is not the biological child of Naoki and Hanako.

Haruna is the daughter of Hanako\'s best friend during high school. The two of them were already like sisters. But when Haruna was one year old, her parents died in car accidents.

Since then, Hanako decided to take care of Haruna, who had lost her parents and had no other family. After a few years, Hanako and Naoki love Haruna like part of their family.

Haruna doesn\'t know about her past, and the Okuihara family intends to tell her when she grows up. On the other hand, Tenku had found out not too long ago, but his treatment of Haruna didn\'t change in the slightest because he already thought of her as his sister.

"Haruna, you\'ll fall if you run like that." The middle-aged woman appeared from behind Haruna. She was Amami Kawano, the next-door neighbor to the Okuihara Family.

Amami was a frequent visitor to the Okuihara family\'s house, and the couple trusted her because they had known each other for a long time. Hanako also often leaves Haruna with her when she and her husband go to work at the restaurant. But sometimes, they also bring Haruna along with them.

"Amami, thank you for helping us look after Haruna. I\'m sorry if I bother you again." Hanako smiled apologetically.

"You don\'t have to worry about it. I also have nothing else to do. Raising a child or two other than my son wouldn\'t make any difference. Moreover, Haruna is a smart girl. I just sat quietly watching her, and it wasn\'t a bother." Amami shook his head. Then she looked at Tenku, who walked into the house holding hands with Haruna.

"How are you, Tenku? Is it tiring after helping your mom and dad at the restaurant?" Amami smiled warmly and gently stroked Tenku\'s head.

"I can\'t be tired just from helping out at the restaurant, auntie! I must train harder to become a Realizer and protect this world from monsters!" Tenku smiled and puffed out his chest proudly. On the other hand, Haruna looked at him with sparkling eyes.

"Ahaha… If Tenku becomes a Realizer, what will Haruna do when she grows up?" Amami looked at Haruna, who clung to Tenku like she didn\'t want to part with him.

"Of course, I will be my big brother\'s bride!" Haruna said cheerfully. Since childhood, Haruna was very attached to Tenku and said she would be his wife someday.

Amami, as well as Tenku\'s parents, laughed when they heard those words. Haruna\'s face reddened with embarrassment, and she dashed into the house while pulling Tenku\'s hand.

"Wait, Haruna! You don\'t have to pull me like that! I will come with you!" Tenku complained, but he kept running after his beloved sister.

"You two don\'t run around in the house." Naoki could only sigh and chase after his two children.

"Okay. I will take my leave since you have returned." Amami looked at Hanako and Naoki and lowered her head slightly. But before she could take a step, Hanako\'s voice stopped her.

"Amami, don\'t forget to come together with Mr. Jiro and Soma tonight." Hanako reminded. Jiro is Amami\'s husband, who works as an employee at a company, while Soma is their son, the same age as Tenku.

"Hmm? What\'s up... Ah! I almost forgot about it! Isn\'t today Tenku\'s birthday!?" Amami clapped her hands and suddenly raised her voice. She remembers Tenku and Haruna\'s birthdays because she and her family often celebrate with them.

"That\'s why you must come tonight and don\'t be late. This time, I have prepared special food and drinks for Tenku\'s birthday." Hanako smiled mysteriously. She knows that Amami has a hobby of cooking and culinary, especially unique foods.

"I\'m looking forward to it! I will come together with my husband and son early!" Amami answered excitedly after hearing Hanako\'s words. Then she returned to her residence, and Hanako went into the house to prepare for tonight\'s event.

Night fell, and the full moon shone beautifully. Right now, the Okuihara family\'s house was noisier than usual. The Okuihara family sat together at the dining table with their neighbors. They are Amami, Jiro, and Soma. Jiro is a middle-aged man with short hair and is not very tall, while Soma is the same age as Tenku, who is slightly shorter than him.

In the living room, Tenku has blown out the candles on his birthday cake, and he is currently feeding Haruna his first piece of cake because his sister keeps whining to get it. On the other hand, Amami and her family enjoyed the food that Hanako served at the dining table.

"Tenku, this is a gift from me, aunt, and Soma. We hope you will like it." Jiro gave a box neatly wrapped and tied with a blue ribbon to Tenku. Among the three people from the Kawano family, Jiro is the one who has the best relationship with Tenku.

"Thank you, Uncle Jiro!" Tenku accepted the gift with a big smile on his face. Then he looked at Amami and Jiro.

"May I open it now, uncle?" Tenku can\'t wait to see what\'s inside the box.

"Of course." Jiro nodded and smiled. On the other hand, Soma looked envious when his father gave the box to Tenku.

"Come on, open the presents, brother! I want to see it too!" Haruna drew closer to Tenku and was also curious about Jiro\'s gift.

Naoki and Hanako smiled warmly at the behavior of the two children. Then they saw Tenku open the box in a hurry.

"Wow! This is an action figure from The Strongest! He was one of the first and strongest Realizers! Thank you, Uncle Jiro! I like it so much!" Tenku shouted happily when he saw the contents inside the box. He hugged the action figure and smiled widely.

The Strongest was one of the Realizers who first appeared and was given that nickname because he was the strongest among the Realizers at that time. Unfortunately, those Realizers had long since died from sacrificing themselves to fight the powerful monsters that appeared during Space Collapse. Because of that, Tenku admired them.

Jiro and Hanako nodded in satisfaction when they saw Tenku liked their gift. When Hanako returns home, she immediately reminds Jiro about Tenku\'s birthday, and the other party quickly buys a present. Luckily, he had a friend who owned a toy shop and was able to order one over the phone for delivery the same day. Coincidentally, there\'s a new Realizer action figure in stock. Jiro knows that Tenku dreams of becoming a Realizer. So he thought the action figure would be a good gift.

"Thank you, uncle!" Tenku smiled while playing with the action figure in his hand.

"You\'re welcome. We\'re glad you like it." Jiro and Amami laughed. Meanwhile, Soma pouted when he saw the action figure.

"Haruna, where\'s your present for your big brother?" Amami looked at Haruna, who kept laughing at Tenku and couldn\'t help teasing her.

"Of course, I\'ve already prepared it." Haruna fiddled with her fingers and averted her gaze in embarrassment.

"Then hurry up and give it to your brother. Don\'t you want to see it too, Tenku?" Amami smiled and urged Haruna. Under the gaze of Amami and the others, Tenku could only nod.

"Before that, you must close your eyes first, big brother!" Haruna glanced at Tenku, and her cheeks turned red.

"Okay!" Tenku nodded without asking any further and closed his eyes. Soon after that, he felt a soft sensation on his cheek and heard the screams of the people around him.

"Ahaha… Haruna is so bold!" Amami happily teased Haruna.

"Aaahhhh!" Haruna quickly ran in embarrassment. When Tenku opened his eyes, Haruna had already disappeared from his sight.

"Okay. Now it\'s time for mom and dad to give you a present." Hanako took something from her pocket. Tenku and the people in the room turned their gazes to Hanako. Their eyes fell on the strange box in her hand.
