-Underworld, Lucifuge castle.
'In the highschool DxD anime wasn't Euclid a mage...' Arthur thought as he used his sword to block a dagger aiming for one of his vital places--his heart.
'He wasn't known for being a close range fighter...sure he did engage in some close range fights but he was mainly known for long range fighting' Arthur thought as he dodged another strike of the dagger wielded by Euclid.
For some Euclia would be difficult to fight because of her speed but for Arthur she wasn't the slightest difficult heck he didn't even had to unseal his power, and the main reason for this was the three tomoe sharingan which kept spinning and keeping track of Euclia movement.
After Arthur came out he decided to test all of his powers that he has unlocked and he found out that one of his powers was a dojutsu which originated from the Uchiha clan in the Naruto anime, sharingan.
"Is that all you've got?" Arthur asked Euclia with a mocking tone as he dodged another one of her attacks.
"Damn it!!, don't act like you're strong!!" Euclia screamed as she continued attacking Arthur with her flame imbued dagger trying her best to hit one of Arthur vitals, her graceful movements has been reduced to a reckless movement trying to kill her opponent testament to the effectiveness of Arthur teasing.
'Ever since his eyes change he has become not only faster but more nimble like he is predicting all my movements!!' Euclid thought as she continued attacking.
'Onee-chan and Father is watching I can't fall their hands!!' Euclia thought as she saw the expressionless look of her sister and the calm look of her father, ' I will definitely win!!'.
"What happened why are you getting sloggish... getting weak perhaps?" Arthur continued with his teasing but prior to his expectations Euclia stopped attacking and closed her eyes.
'Huh...why did she stop?' Arthur thought, but he wasn't only the one who was surprised.
Grafiya raised one of her eyebrow as she saw that Euclia stopped attacking.
'Has she given up?' Grafiya thought.
"Here it comes" Lucifuge said with a gleeful voice making Grafiya to look at him as she didn't understand why her father sounded happy but all her confused look vanished as she felt a burst of Mana coming from Euclia making everywhere icy cold.
"Here I come!!!" Euclia roared as she dashed towards Arthur with great speed.
*Booom!!!*
"..."

Chapter 7: Friendly duel 2
****************************************
'I see so she enhanced herself with a technique...' Arthur thought as he jumped upwards avoiding Euclia freezing horizontal slash.
'Not only her physical prowess and demonic magic but also her class has been increased..' Arthur thought as he used instant movement to avoid Euclia dagger which she thrust forward aiming for his throat.
Apart from her powerup which increased all her attributes Arthur also noticed that Euclia elegant movement had returned as he continuously dodged her ice based attack.
'Just like a dancing-killing machine her movements is fluid with hardly any flaws and also fast' Arthur noted as his lips rose up in a smile.
'Even if she's fast my sharingan can still keep up with her' Arthur thought as Euclia used a speed fast enough to look like a blur to the naked eye....but for Arthur she was moving at a jogging pace.
'Why can't I land a hit on him!!' Euclia screamed in her mind as she continued attacking Arthur mercilessly each of her attack meant to hit him in his vital point.
'This should do for now' Arthur thought as he used instant movement to create a distance of twenty meters between him and Grafiya.
"I will stop fooling around be ready I'm going to attack now" Arthur said as he sheathed his sword and got into a drawing stance.
The only reason Arthur agreed to the duel was to know how to use his power effectively. After all he can't just go to war and learn how to use his skills there it might bring consequences he didn't like.
(A/N: Even though he have the memory of the skill his body has not yet experience, it is like a three month old toddler with the memory of blacksmithing)
'[Sun breathing Eleventh form: Dead calm]!' - Arthur.
Arthur bent his legs slightly ready to attack but Euclia was faster.
"Oh, no you don't!!" Euclia shouted as multiple blue magic circle with the Lucifuge clan logo at it middle form at her former at her back.
'[Frozen Bullet]' -Euclia.
*Swoosh!!*
Numerous frozen icicles slowly came out of the magic circle before shooting towards Arthur with a great speed intended on killing him.
'[Sun breathing Ninth form: Heart raging tide]!'-Arthur.
Arthur moved in zigzags leaving a trail of water as he dodged Euclia attacks and appeared by her side then used another skill.
'[ Sun breathing fifth form:Water wheel]!!'
Arthur spinned as his sword which was coated with water act like a water wheel before coming to an abrupt stop inches away from Euclia neck making a cold sweat drip from her cheek.
'I-i couldn't sense him with my devil sense?!!'- Euclia.
