"Karasu Tabito, the 'Assassin'. After using his sharp powers of analysis to designate the other team's weakest player. He tries to thoroughly crush them until the end of the game"

It appears that Hiori and Karasu are from the same youth team in Kansai. I missed this minor detail while reading the manga.

Hiori then told Isagi,

"The one thing I can say is to give up on trying to hide your weak points, and challenge him with your strong points."

...

Restart.

Rin passed to Shidou.

Shidou:
"Let's go with the same pattern as before, Isagi-chan."

Shidou passed the ball further back to Isagi, but Karasu had catches up to Isagi while keeping pace with him.

Isagi must've thought to force a pass to Rin, but it was impossible.

Karasu used his hand and made body contact to prevent him from passing.

Karasu:
"Told ya, you're mediocre once it comes to one-on-one."

Karasu then steals the ball from Isagi.

He should've noticed by now, that the crux of all Karasu's plays is the handwork that lets him control the distance to steal the ball.

Karasu:
"You're dragging your team back, Isagi."

Nanase:
"I'll move in to cover!"

Nanase went to stop Karasu alongside Shidou, it's a 3-on-1 situation.

I signalled Shiguma to cover the gaps I left behind with my hand.

I then ran across the field with my newly acquired weapon from Loki.

Karasu:
"There you are."

Hiori:
"Oh no! look out Rin-kun!"

In the manga, Otoya fooled them with his stealthy steps. I replicated the scheme with something more or less the same. A speed that nobody can match.

Rin:
"Tch!"

Isagi:
"He got behind Rin!"

I then finessed the ball to the top right corner of the net.

[1] - [2]

Nishioka:
"What do you think? Am I late?"

Karasu:
"You were a second late."

...

Restart.

Isagi:
"Let's go, Rin! Use me again!"

Karasu:
"Just try it."

Rin ignored Isagi and passed to Hiori instead.

They were able to get past Shiguma and Saramadara with their one-two passes.

Nishioka:
"Princess! Fall back!"

Chigiri arrived on time and went one-on-one with Rin.

Shidou:
"Come on. Give it here, No. 1!"

He'll use Shidou's movement as a cover then shoots the ball when he's out of the goalie's view.

As Rin shoots the ball, I dived forward and blocks the ball with my head.

Shidou:

Nishioka:
"Since the very beginning of Hiori's and Rin's plays."

The ball landed on Karasu.

Karasu:
"You left me with such a burden."

Both Hiori and Shidou went upfront to help with Rin's attack, so their defense were left with Nanase and Isagi.

Karasu:
"But.. it was still plausible to complete."

He smashed the ball to the back of the net from the distance.

[1] - [3]

This field was no more than playground for the both of us.

...

Restart.

Nishioka:
"What's now, Rin-chan? We've been together on the Second Selection for days. I knew you more than anybody in this field."

Rin ignored me.

Our formation was imperfect.

Because Karasu had to deal with Isagi, our midfield was quite open. We're only keeping this formation because I was confidence with Chigiri and my speed.

It'll be a nuisance if they find out about it.

Rin passed the ball to Hiori.

Nishioka:
"Are you planning on those one-two passes again? Same trick won't work twice I told ya."

Hiori then lobs the ball far in front.

What was he thinking? I'm faster than Rin and I'll get the ball back before he did.

I'm now side to side with Rin, I drop my body and sweep the ball with my left foot.

Nishioka:
"Counter attack!"

Ah.

Before the ball landed on the ground, Shidou leaps into the air with perfect timing. He twists his body mid-air and executes a flawless bicycle kick.

The ball curved past the outstretched hands of Blue Lock Man.

[2] - [3]

Nishioka:
"My bad y'all."

Chigiri:
"No, that's my fault. I should've dropped back and deal with him."

Karasu:
"Our formation is not working anymore, I suppose this is a better option."

Shiguma is far on the back alone, Chigiri and Saramadara become our dual defenders, while Karasu and I are up front.

...

Chigiri:
(I bet Isagi is thinking the same thing.. Aside from the top six of each team, no one else has been able to justify their existence, myself included. To the Top 6, we're replaceable and nothing than just a pawn. That's why right now.. I should just focus on showing what my weapon can do!)

Restart.

I passed the ball to Karasu, it also seems like Team A is playing more offensive now.

Shidou already went to steal the ball from Karasu

Karasu:
"Just try to take it, No. 2."

They're also more watchful with my speed now as Nanase was tightly guarding me.

Noticing that, Chigiri sprinted towards a wide-open space on the right flank

Nishioka:
"Pass to our princess, Karasu."

Karasu:
"I know, I know."

Karasu crossed the ball to Chigiri.

Isagi tried to catch up to him, but it's no use.

As Chigiri traps the ball, Rin is already right in front of him.

Rin:

!

Chigiri smirked as Rin said that.

Chigiri:
"That's a speed that matches mine, we're basically a cut from the same cloth, Nishioka!"

Chigiri crossed the ball curving over Rin to the middle.

Nishioka:
"I like that."

I heads the ball to the net.

Team A Team B
[2] - [4]

Our victory became crystal clear.

Nishioka:
"You should keep passing to me princess."

Karasu:
"We can use this one."

Isagi:
(Chigiri.. he gave those two new attack option.. and made them acknowledge his worth!)

Nishioka:
"Hold on a sec, I wanna ask something."

Karasu:
"..What is it?"

Nishioka:
"Can I be selfish for once and goes crazy after this?"

...

Restart.

Shidou passed the ball to Rin, who passed it again to Hiori.

They're focusing on ball possession, I guess.

Hiori is rapidly turning his head to verify the situation around him, he reminded me of myself.

He's trying to force himself to enter the game of the top 6 using his weapon like what Chigiri have done.

Isagi noticed that too, so he ran in front of the goal, where he can use his direct shoot.

Karasu:
"Not gonna happen, you dunce. I can see through that."

Hiori noticed Isagi's movement and curved the ball to Isagi..

Nope, it's to Rin.

Here's the funny part.

Shidou:
"Nah. That's mine."

Nanase:
"Aah! what are you doing?!"

Chigiri get the loose ball and passed the ball to me.

Karasu:
"It's time."

Chigiri:
"Yeah."

"Time to go wild."

Once I received the ball, the field and the players on it seems moving in slow motion.

I took a deep breath.

With a swift turn, I left Nanase in the dust using Loki's- nope, my explosive acceleration.

Chigiri was already sprinting down the left flank.

I lightly flicks the ball.

Nishioka:
"We win, boys."

As Blue Lock Man dived to catch the ball, I chipped the ball high enough to get past him.
