You fight Byleth

Byleth: what a waste of your talents boy, you could have been a great adventurer

Byleth: oh well

Byleth swings again to finish him off

when she notices a fireball being hot at her so she dodges

Byleth: another one

Aiden: sorry can't have Stark die, well not yet at least

Byleth: well aren't you a nice team member

Byleth: and what do you mean by not yet

Aiden: he can die once he's watched me fuck his teammates

Byleth: ha, you joined the team just to fuck those two mages

Aiden: yeah so

Byleth: aren't you interesting

Aiden I am, almost as interesting as you

Byleth: what do you mean by that

Aiden: I know Fubuki hired you and your bandits to find her husband's treasure

Byleth: you do, do they know

Aiden: no only me

Byleth: so what you want a cut

Aiden: I doubt Fubuki will be happy with just a third of her husband's treasure

Byleth: ha, I'm not giving the treasure to her, I'm keeping it all for myself

Aiden: really so tell me if I help you find it how big of a cut would I get

Byleth: 30%

Aiden: only 30?

Byleth: I have been here for weeks i deserve the biggest cut

Aiden: sorry no deal

Byleth: you would walk away from such a good deal

Aiden: I know the treasure is beyond that door, otherwise you wouldn't have run to here, so know I'm going to beat you, and give Fubuki the treasure so she'll give me some of it and her loyalty as one of my allies

Byleth: it's your funeral

Byleth swings her sword which sends the whip-sword flying at you

Aiden: no wonder Stark couldn't deal with this

Aiden: DEVINE REFLECTION

The sword bounces off the shield and goes back to Byleth with twice the speed and power

Byleth: WHAT?

She tries to dodge but is hit with her own blade

Byleth: FUCK

Byleth: YOUR ABLE TO SEND MY ATTACKS BACK

Aiden: yep

Byleth: then I just need to make sure you don't have time to cast that spell

Aiden: true but what will you do about this

Aiden: OBSCURANT WALL, TRANSIENT WALL & HONORABLE WALL

Aiden: even if the immunity of OBSCURANT WALL expires the other two skills will give me enough defense to take on that sword

Aiden: come and get me bitch

Byleth: FINE LET'S DANCE

Byleth comes at you with everything she has

you two fight for 10 minutes, but in the end you are victorious

Aiden: goddamn you're the first to actually give me a struggle congratulations Bitch, I'll give you the reward you deserve later

You pick up the Sword of the Creator

Aiden: and this now belongs to me

A message pops up

Congratulations you defeated Byleth and claimed the Sword off the Creator for yourself
