Kai decided to help out as well, because he was getting tired of talking to his sister and realizing how pointless it was to discuss the past.
When a beast invasion occurred, Kai's mother and father, who were the heads of a particular noble family, died defending that land and were killed by a demon legion. As a result, Kai, the sole heir of the previous household, was sent to a remote corner of their country town. To ensure this, he would not participate in the family head race; after all, with Seraphina on his side, they couldn't assassinate him.
Seraphina was a level 5 magus talent and a level 4 Ryoshi Magic Swordsman. Due to this, she was also called the youngest talent in the entire county.
But Kai knew she was still hiding her strength, and her true strength was already beyond the knowledge of those in his country, including her teacher, who was also known as the Berserk Angel on the battlefield.
"Seraphina, sister, I am still feeling tired, so I will go back to my room for some rest." Kai could tell from the food, which appeared to be extremely lavish, that this feast was something they must have prepared for his recovery.
"Okay, but take Eliana with you; she will look after you for the time being, and given the chances that others might take action against you, I want you to have at least one of us sisters by your side at all times."
While Eliana appeared to be a little worn out herself, Seraphina smiled lightly as she observed her. Eliana jumped up from the chair and smiled to mask her weariness as she walked next to Kai.
Kai could tell that Eliana, who was still at least two to three years younger than him, was extremely exhausted, but he could not admit it in front of Seraphina's eyes, so he made the decision to take Eliana with him.
"I will let her rest in my room, and with that, I do not think that sister Seraphina will be angry about them." Kai thought as he jumped down from his chair, walked beside Eliana, and took her hand.
"Let's go, sister Eli." Eliana's eyes briefly flashed in surprise, but she continued to walk alongside him while grinning widely.
As they walked back to Kai's room, Kai and Eliana talked and laughed. Kai told her stories about his adventures, and Eliana told him about her dreams for the future. They were both tired, but they were also happy.
While talking to each other, Kai and Eliana had some fun. Kai also recovered while lying on his bed, as his body's natural healing process kicked in and he was becoming less and less exhausted, while Eliana slept soundly on his bed with Kai laying next to her.
Kai was rendered helpless as he stared at his sleeping sister's face and realized how adorable she was even before they became siblings.
"This little sister of mine will undoubtedly be a devastating beauty in the not-too-distant future; given her age of 9, she already looked this beautiful."
Kai muttered, thinking he was only 11 years old, along with Amara, who was in the same age group, but she was still 5 months bigger than him.
Seraphina was the only adult in this household over the age of 15, and most noble children attend a specific Royal University of Education. Those who have passed through that stage have the legal right to be called adults.
Despite the fact that Kai was only 11 years old at the time, he was required to attend Royal University, whose Magic Knight branch is located in Tome Hall Mountain Base City, in just around 3 months.
However, the fees required to enter that university are very high, and Kai did not have the talent in magic to enter the university with a scholarship like his two sisters did, but it was thanks to Amara that he had obtained a spot for himself.
Amara was therefore here to transport Kai and Eliana to that city as soon as the town had been established, given that the school's security was the best option for Kai's safety.
Kai woke up to the sound of a voice.
"Welcome to the Multiverse Guild System."
Kai opened his eyes and saw a virtual screen in front of him. The screen was filled with text and images.
"What is this?" Kai asked.
"This is the Multiverse Guild System," the voice said. "It is a system that will help you to become the strongest you can be."
"How?" Kai asked.
"The Multiverse Guild System will provide you with access to a variety of resources, including training, equipment, and information," the voice said. "It will also allow you to connect with other players from all over the multiverse."
"That sounds amazing," Kai said.
"It is," the voice said. "But it is also a lot of work. If you want to succeed, you will need to be dedicated and disciplined."
"I am ready," Kai said.
"Good," the voice said. "Your journey begins now."
When Kai woke up in his room, Eliana was sleeping blissfully next to him. He touched her cheek and tried to pull his hand away, but his beloved sister was using it as a pillow and did not appear to be waking up any time soon.
"Hehe, it is the first time I have seen her sleep like that beside someone other than me." Seraphina's voice could be heard as Kai struggled to move, and as he turned to face her, he noticed her.
"Hmm, both of us were tired and slept like this, but sister, how long have you been here? Then help me out a little." Kai spoke in a low tone at Seraphina's chuckle as she walked toward them.
"After all, my little sister is just pretending to sleep right now, having woken up after you tried to touch her cheeks." Kai was stunned as he turned to look at Liana's face, whose cheeks were about to burn like a red tomato.
After which, Liana woke up with a pouting face as she turned to look at Seraphina and ran back to her room without looking back.
"Haha, what a cute little sister, right? She is way too precious and cute for me to end up messing with her a little from time to time."
Looking at Seraphina playing with Liana like that, Kai realized why little girls are so concerned about their big sisters. Seraphina had something else on her mind, so she left, leaving a small portion of food she had purchased for him.
On the side of the food, there were several books about Magic Knight that Kai had requested, given that in his previous life he had practiced Kenjutsu and Taekwondo for physical fitness.
'Hmm, swordsmanship in this world is not close to being refined at all, it is all arbitrary and useless, if it is compared to the one martial artist in my world has worked hard for several generation.'
