Sword Art Online Crossover: They're all close friends, how did I become a player?

"Ha, huff... huff... huff... so tired."

On the tennis court next to the villa, several teenagers were lying sprawled out.

After lunch and a rest, the members of the tennis club were pulled up for special training by Yu Bai, who had a gentle smile on his face, and Taki Oginosuke, the current tennis regular and the tennis club's accounting manager.

When the group first saw Yu Bai's training plan for the next seven days, they all felt dizzy. Even Atobe Keigo and Oshitari Yuushi doubted whether they would be able to leave the mountain in seven days.

If Atobe Keigo and Oshitari Yuushi were like this, then Mukahi Gakuto and Akutagawa Jiro were even more so. The two clung to Yu Bai's legs and wept, hoping that Yu Bai would give them a reprieve, but Yu Bai gently but firmly refused.

Yu Bai said that even Yagen, who was working with him, could complete this amount of training without batting an eye, and everyone who heard this said it was impossible.

They looked at Yagen Toushirou's slender limbs and petite body, his bespectacled face and refined demeanor, and he seemed like the type of academic genius who had nothing to do with sports.

However, in order to prove the truthfulness of his words, Yu Bai directly had Yagen Toushirou undergo special training with them.

As a sword spirit whose word was law, Yagen Toushirou agreed without hesitation.

Yu Bai even told Yagen Toushirou in his room after lunch, "Don't hold back in front of the Hyotei Tennis Club and others, just be yourself."

Yagen felt a slight pang of sympathy for the tennis club members who were completely unaware of the situation, but he replied without hesitation, "Understood, Daisho."

In the following days, everyone began grueling training. At first, everyone thought it was really putting the child in a difficult position by having Yu Bai make his younger brother train with them.

As it turned out, they were overthinking it. Instead of worrying about whether Yagen Toushirou could finish the training, they should have been more concerned about their own survival.

after all……

When they were struggling to run their sixth lap of the mountain road, panting heavily from exhaustion.

Yagen Toushirou ran the entire course without changing his expression, and afterwards he still had the energy to prepare snacks for Yu Bai.

As they stand in the turbulent water, struggling to overcome the resistance from the water, they slowly practice swinging their rackets.

Yagen Toushirou completed his swing practice quickly and with great ease, and even took the opportunity to catch a fish in the water and give it to Yu Bai.

When they are frantically dodging 10 tennis balls launched rapidly at the same time on the tennis court, and trying to hit the tennis balls with a specially made cross racket.

Yagen Toushirou moved nimbly across the court with speed that seemed inhuman, and not a single tennis ball hit him; in fact, he was returned to the net one by one.

Then he ran up to Yu Bai and secretly asked for praise. After being patted on the head, he was clearly in a better mood.

Sometimes, even Mukahi Gakuto wondered if he saw a backdrop of cherry blossom petals falling behind the child.

Although Yagen Toushirou had never learned tennis and used a regular racket.

But knowing he was a beginner, seeing him easily dodge 10 high-speed tennis balls and even return the ball felt even more unreal to them.

……

It must be said that Yu Bai's decision to have Yagen Toushirou train with Atobe Keigo and the others was extremely effective.

Whenever someone feels like giving up, just look at Yagen Toushirou next door and they'll stubbornly persevere.

No matter what, I can't lose to a child so much younger than me, right? Wouldn't that be too embarrassing?

Of course, they didn't know that the person Yu Bai used as a source of stimulation, Yagen Toushirou, was not human at all, but a knife spirit with a youthful appearance but an age old enough to be their grandfather's grandfather's grandfather.

No matter how good Atobe Keigo and the others' physical abilities are, they can't compare to the sword spirit who is a tsukumogami.

After all, the enemies they faced were the powerful Time Travel Army. Fortunately, the one who came with them this time was Yagen Toushirou, the chief of the short swords. If it had been the cross-dressing master Ran Toushirou or the cute and cuddly Gokotai, these people would probably have been crushed.

"Ahem... It seems that Senior Yu Bai's training plan has become more intense again."

Ootori Chotaro was panting heavily. Shishido Ryo, lying next to him, was too tired to speak. He could only blink in agreement with Ootori Chotaro's words.

"And Yagen, is his physical condition even human? One day I'll overthrow him!" Hiyoshi Waka, deeply affected by Yagen's words, clenched his fists and said.

Yes, he had a lot of presence, if you didn't see how powerless he looked lying on the ground.

"But Hiyoshi... Yagen is younger than you, isn't he? How can you, a subordinate, defy your superior?"

"..."

Akutagawa Jiro spoke with an innocent expression, unaware that his words had stabbed Hiyoshi Wakashi in the heart.

"Not fancy at all. Isn't that right, Kabaji?"

"……Yes."

The only person still able to stand was Atobe Keigo. Actually, he couldn't stand up, but sometimes, he still carried a heavy burden as Hyotei's top star. So even though he was so tired he couldn't move his fingers, he still forced himself to lean against the wire mesh.

You want me to lie on the ground like these guys, all disheveled and pathetic? Don't even think about it!

"Huff...huff...Yushi, I feel like I'm going to die. I have no strength left. Waaah! Why does Yu Bai turn into a demon king whenever he trains us? He's usually so gentle. Now he's a devil! A devil!"

Gakuto Mukahi clung to Yuushi Oshitari's sleeve and wept bitterly before his partner. Because of Gakuto's obvious weakness in physical fitness, Yu Bai had been specifically targeting this area in his training. This caused him to feel, during every training session, that he was about to see his great-grandmother.

Although he could feel a significant increase in his physical strength, which was a good thing, he didn't want his great-grandmother to go through all that trouble to see him every time.

He feared that one day his great-grandmother would kindly take him away.

"Ahem, Gakuto, I advise you not to say anything more." Yuushi Oshitari, who had inadvertently glanced over and saw a figure standing not far away, was trying to save his partner.

"Huh? But that's right, you see, Yu Bai is usually so gentle and kind, but when he trains us, he turns into..."

P.S.: Some people are confused about whether Yue Ren's name is Mukahi or Hinata. I'll use the name Mukahi from Baidu Baike (Baidu Encyclopedia) here. (Yue Ren's full name is むか(向)ひ(日) がく(岳)と(人).)

I'm not making any more changes, or I'll get confused myself QAQ.
