Evening at the academy.

(Y/N) along with tori, cathy and caswell are watching a duel between yuma against bronk.

Its been a day after yuma lost against shark and by that time yuma kept dueling against bronk since school ended.

Caswell: I thought yuma would have just gave up dueling after a devastating loss against shark yesterday?. Said with a questionable look.

Y/N: Wrong caswell he's never gives up dueling even he lost miserably. Said with a neutral look.

Then yuma lost again.

Caswell: That was twenty loses in a row. Said with a neutral look.

Cathy couldn't help but worry for yuma being like this.

Yuma gets up.

Yuma: Nice move bronk, let's go again. Said with a smile.

He sigh and start to walk away.

Bronk: I had enough, I'm going home. Said with a neutral look.

He got his bag and walk away.

Then (y/n) and tori went after him after yuma challenged caswell.

Both of them catch up to him.

Tori: Bronk what's wrong?. Said with a worried look.

He stopped and sigh.

Bronk: Its just that I don't like the way yuma is, he broke his promise not to use the number cards. Said with a serious look.

Y/N: I know that bronk but you didn't saw yuma hesitated in that moment. Said with a neutral look.

He looks at (y/n).

Y/N: He never breaks a promise that I know him too well but reginald wanted him to summon the very card that beaten him so bronk tell me this, is a promise is more important than to help someone who said a request to get back to the game. Said with a neutral look.

That made him thought about it long and hard every word he said.

Bronk: But (y/n) he broke his promise. Said with a serious look.

Which made him sigh.

Y/N: Seems you don't know that dueling is not to make promises it is a honored game and from the heart, if you don't understand that then you quit being a duelist. Said with a serious look.

Which made him widen his eyes with a surprise look and tori gasp hearing that.

Y/N: Do you really think that promises can get you to the top of the dueling world, it isn't and trust me bronk it will drag you down. Said with a serious look.

Then he walks away passing him.

Both of them look at his direction and the words he said.

Tori gotten more worried for (y/n) acting like this.

Skip.

At night in the tsukumo home.

(Y/N) sitting on his bed in thought about shark.

He looks at the picture again with a sad expression.

Then thought about it the past.

Flashback two years ago.

(Y/N) running quickly at the hospital heading to a specific room.

Then he entered the room and see shark and on the bed the girl bandaged up.

He is shocked to see her condition and went by his side.

Y/N: W-What happened?. Said with a shocked look.

Shark didn't say anything but look down in sadness.

(Y/N) looks at him.

Y/N: Reginald tell me who did this?. Said with a worried look.

He sigh.

Shark: I don't know I got a call an hour ago from the hospital about her got hurt and went to a coma. Said with a sad look.

Which made him wide his eyes.

???: (Y.............../n). Said out of nowhere.

Both of them widen their eyes and see the girl moving her right arm up.

(Y/N) grabbed her hand and squeeze a little.

Y/N: I'm here rio. Said with a worried look.

Her hand squeeze his hand and she made a weak smile.

Rio: I........knew......you........be....here. Said with a weak smile.

Shark quickly left the room to get the doctor.

Rio: (Y.../n)?. Said with a concern voice.

He held her hand with both of his.

Y/N: I'm here rio and listening. Said with a sad smile.

Rio: Please....promise....me....look.......after.......reginald....be...there....for.....him. Said with a weak smile.

Tears forming in his eyes and nod.

Y/N: Don't worry I will look after him I promise, just gets some rest you will be fine. Said with a smile.

She smile more.

Rio: I.....know....you....will. Said with a smile.

Then the doctors came in with shark and check on her but she went back to sleep.

Flashback end.

He look at picture one last time and sigh.

Y/N: I'm sorry rio, I failed my promise to you. Said with a sad look.

Unknown to him that astral is watching him from the attic entrance and heard what he said.

Then went back to the key to continue his investigation of the ship.

Then yuma noticed bronk and ran towards him.

Yuma: Hey bronk. Said with a smile.

He sigh still what (y/n) said to him.

Bronk: Not this time yuma. Said with a neutral look.

Then he skate away which yuma is annoyed.

Yuma: Fine then I'll find someone else to duel. Said with a annoyed look.

Then astral appeared out of the key.

Astral: No yuma you can't win against anyone. Said with a neutral look.

Which yuma looks at him annoyed.

Yuma: Why is that astral?. Said with a annoyed look.

Astral: After you lost against shark all your dueling is getting sloppy and predictable always attacking which is why it is getting to you to lose focus and think of a plan. Said with a neutral look.

Yuma: What do you mean?. Said with a serious look.

Astral: Shark is a good duelist but he took his time to analyze your dueling skill and deck, which comes with a question how much you know his skill and deck?. Said with a neutral look.

Which got his attention and think.

Then he looks at his brother to ask something but to his surprise he just went ahead.

Yuma: Hey bro wait up. Said with a surprise look.

But he continued walking but he heard their conversation.

Yuma walked by his side.

Yuma: Hey bro can you t-. Before he finished his sentence.

Y/N: No I won't tell you everything about reginald so drop it. Said with a neutral look.

Which he's surprised to hear.

Yuma: But bro you know he's with those guys aren't you worried since you know him since childhood?. Said with a questionable look.

He sigh and looks at him.

Y/N: Indeed I am but there's nothing I can do to change his mind. Said with a neutral look.

Then he walked towards them and heard they are reading about shark at the nationals last year, which he quickly walk to the and turn of the computer.

Yuma glare at him.

Yuma: You can't leave him like that bro you know him better than anyone and it is wrong for you to leave him like that. Said with a worried look.

He grit his teeth a bit which tori noticed.

Y/N: *sigh* I know yuma but he made his choice. Said with a neutral look.

Then he walks away leaving them.

Tori knew he is hiding something and went after him.

Later.

Both of them walk together out of the school heading home.

She looks at him.

Tori: (Y/N) you know what happened at the nationals isn't it?. Said with a questionable look.

He looks at her.

Tori: Look I know it is not my business to get involved with shark but I'm worried about you, the way you are now is not good at all and you keep distant with us. Said with a worried look.

He sigh knowing she's right.

Before he could say anything.

???: HEY YOU!!. Yelled out of nowhere.

Both of them look to see the young man from the gang shark hangs out with.

He stood in front of them which (y/n) stood in front of tori just in case is some trick.

Y/N: What do you want?. Said with a serious look.

Which (y/n) let him go and quickly ran of.

Tori: WAIT (Y/N)!!. Yelled with a worried look.

Y/N: Sorry tori but I have to go. Said with a serious look.

He continued running.

Thinking of Rio still in the hospital.

Y/N 'thought': Rio I may have failed my promise to look after him but I will do whatever it takes to get him back at the right path that I promise. Said in his mind with a serious look.

While he continued running not knowing a faint glow coming from his deck box from a certain card like it feels its host emotions.

Skip.

Late at night.

Outside of the museum.

Three bikes coming by and stopping right of the outside walls of the museum.

Scorch, chills and shark got of their bikes.
