Looks:

(I shouldn't need to mention this but none of the art in this or any of the books I make are mine. All credit goes to the original creators. Also this image is not a good representation of what his personality is)

(The readers left eye is covered by some wrappings)

Personality: Not really emotional and doesn't show his true personality around others.

Likes: Doesn't like much

Dislikes: Demons

Breathing Style: Breath of Time
(I saw this on a post and loved the idea so I'm borrowing it credit goes to the person who came up with the idea)

1st form: Aeon Assualt: User dashes towards his
opponent and makes a quick but powerful horizontal
slash

2nd form: Necro Flash: User moves quickly behind his
opponent (so fast it looks like he teleported) and slashes their neck

3rd form: Time Bolt: User moves so fast (as if he's
teleporting) and slashes the demons neck (works best
with multiple enemy's)

4th form: Illusionary Hoax Velocity Strike: User moves so fast he creates multiple speed mirage's to trick the
enemy of his position and strikes him

5th form: Time Spiral Whirlwind: User slashes randomly in all directions in a spiral spiral like pattern (works best when surrounded by enemies)

6th form: Tempus Ripper: User makes random slashes
that cut anything and everything in front of it

7th form: Tempus Fusion: User creates a crater every
time he slashes with this form

8th form: Pendulum: User slashes
quickly in the blink of an eye so many times the opponent is seen in little bits like a bag of chips

9th form: Past Aeon Sensor Bane: User stops and uses
his hearing to detect even the slightest of vibrations to
discover the whereabouts of his enemies.

10th form: Twisting Protection Fusion: User slashes in all direction to protect himself from attacks coming in all directions

11th form: Chrono Whirlwind: User builds up speed and: jumps into the air and starts spinning to gain enough

12th form: Clock strikes midnight: This is the users
strongest move, the user moves constantly around the
enemy so fast he is undetectable and building up speed
which in turn, allows him to also build up strength while also confusing the enemy of your position for 1 quick and but power strike that creates a shock wave so powerful, it creates massive crater. (This technique is similar to thunder clap and flash six fold however the user of this form not only builds up speed with every movement, but he gains strength as well)

13th form: Genesis Rise:

(But it doesn't have the flame detail, instead it would look like there are multiple swords as the different points starting from the initial point of the swing and at the end where the sword stops, in a way showing where the blade was at different times.)

14th form: Skipping Step Slash

(The part where King Crimosn dodges, then follow it up with the part where King Crimson Chops the guy)

15th Form: Time of Death:

(Basically what the assassin did to saber)

16th form: Temporal Needle Thrust:

This is the stance Y/N takes when using this form. The form requires him to fully focus on the direct of his attack as he can not turn our alter the course. Once Y/N has readied his strike, in a burst of speed appears infront of his target and thrusts the blade into their chest. Y/N moves so fast that multiple transparent versions of himself appear behind him.

17th Form: Conclusion Decent:

Like this, minus the flames and instead it appears like there multiple Y/N's both infront and behind Y/N as he's descending down at his opponent, representing all the moments in time Y/N was or will be in the attack
