Upon hearing Yusei's words, the couple simultaneously put down their chopsticks, exchanged a glance, and showed some helplessness.
In the end, it was Kanako who explained with a bitter smile.
"Shiro really hates school. I also want her to go, but..."
Hearing this, Yusei was taken aback, 'Had she already been isolated and come to hate school?'
Shiro looked up at Yusei. Her placid red eyes showed no excessive emotional fluctuations. Her small mouth, still dotted with a bit of mousse powder, opened slightly.
"I don't want to go to school. I just need Nii to be with me."
The way she said it was far too calm for an elementary school student. Shouldn't elementary school students refusing to go to school involve crying, making a scene, and threatening drastic measures?
Well, Shiro was different.
After learning that Shiro already hated school, Yusei let go of the idea of sending her there.
But what Shiro said earlier was indeed correct.
'Hmm, truly, having me, her Onii-chan, is enough. Little friends aren't necessary.'
After dinner, Yusei exercised in his bedroom… push-ups, sit-ups, and other exercises.
He needed to improve his physical fitness now, so necessary exercise was required.
Shiro curled up on her small bed watching TV, not particularly curious about Yusei's exercises, just glancing over occasionally.
"99... 100!"
Finally, divided into five sets, Yusei completed the goal he had set for himself today.
One hundred sit-ups, push-ups, and frog jumps, divided into five sets of twenty each.
It wasn't a lot, but for Yusei's otaku-like body, it was already overload.
'So exhausting. This guy's physical fitness is too poor. Plus using Ryugasen multiple times during the day, my whole body doesn't want to move at all now.'
Lying on the bed, Yusei panted slightly. Right now, he just wanted a hot bath and a good sleep.
But he still had things to do. After resting a bit, Yusei closed his eyes and entered the system.
He remembered he had completed a system task, and now it was time to claim the reward.
In the system, the task related to sparring with Koken was there, and the completion status showed 'Complete'.
[Will you claim the task reward?]
'Claim.' Yusei silently chanted in his heart.
Instantly, Yusei felt the reward item description appear before his eyes in the illusory world.
[Congratulations, Host, on obtaining the item 'Hiten Mitsurugi-ryu Training Insights'.]
[Hiten Mitsurugi-ryu Training Insights: 1. Greatly increases the holder's speed in practicing Hiten Mitsurugi-ryu and enhances comprehension of its training. 2. Resets the usage limitations of Hiten Mitsurugi-ryu.]
Seeing the task reward, Yusei felt slightly disappointed.
It wasn't that he was disappointed with Hiten Mitsurugi-ryu itself, but rather with the function of the reward item.
'Even an item that boosted sword technique power would have been better. What's the use of increasing training speed? With my Sharingan, I could just copy anything I wanted to learn.'
Yusei felt this reward would have been worse than getting something like a stamina potion.
A stamina potion could at least improve his physical strength, but this 'Training Insights' overlapped with the Sharingan's ability.
'But having something was better than nothing. And the second ability seemed interesting… usage limitations? Did it mean breaking through the physical stamina limitations on using Hiten Mitsurugi-ryu?'
Actually, he had guessed a bit that he might obtain an item related to Hiten Mitsurugi-ryu.
Because when the task was issued, the reward was shown as '???'.
Probably, the task reward was based on what he obtained from Koken.
If Koken hadn't taught him anything, the reward might have been something else.
But since he gained the opportunity to practice Hiten Mitsurugi-ryu, he obtained an item that assisted with training.
'So, does that mean the system helps me become stronger rather than directly giving me super powerful strength? Strength still relies on my own training.'
Yusei secretly speculated about the system, but the specifics still needed verification.
He had already gained a lot today, so Yusei had no regrets.
Next, he practiced the mind-training technique given by Koken for a while, then took a bath, lay directly on the bed, and prepared to sleep.
