One year and four months later in the mountain of the Arcus estate, we can see Frost a 10 years old boy and Ash his father facing each other in a spar, there the field was frozen and deep slashes and holes can be seen everywhere. They have been facing each other for 1 hour now, when suddenly Frost stop and the sword in his hand disappears and the portal behind him closes, seeing this Ash become alert even more he knows that this is not over because his son is not even tired.
looking at his father "Father now i am going to show you my ultimate ability this ability will show you all the hard work i have put in to create all these swords." Frost said as he chanted
"i am the bone of my swords
steel is my body and fire is my blood
i have created over a thousand blades
unknown to death nor known to life
have withstood pain to create many weapons
yet, these hands will never hold anything
so as i pray,
UNLIMITED BLADE WORKS"
Once he finish the chant in front of Frost eyes there is barren land with thousands of swords sticking in the ground. seeing this Ash eyes went wide because he was unsure what going to happen next, when suddenly he heard his son said "Rise" and what he saw in front of him make him speechless. All the thousands of sword float off the ground and all them was pointing at him in all directions, covering him from bottom to the top. looking at this there was no way to escape he raises his hands and said "i give up, that's some technique there, i can't believe you can control all the sword in here."
"well it does have its own draw back, for example every hour i use this field i can't use it again until 2 hours has pass." Frost said as he rubbed the back of his head. One year has passed and during that one year he has managed to develop his ability, he has created 3 different abilities. The first one is called lucky sword roll, it's similar ability to kite but instead of different weapons he has different swords with different abilities ranging from slot number 1 to 5.
[Number 1] = [Give the user the ability to control ice]
[Number 2] = [Give the user the ability to control fire]
[Number 3] = [The sword extends at the speed of light and if it cuts the person that person is forcefully put in a zetsu condition, unable to use nen for 1 hour, it also inject the enemy with a toxin that destroys cells within seconds killing them in under a minute]
[Number 4] = [Give the user the ability to control lightning]
[number 5] = [ when the user dies, there will be sword that will appear behind the one that is responsible for the users death and stabs him/her, killing them while absorbing that person life force and transferring it back to owner, Resurrecting him from the dead. However after the Resurrection he can't use nen for 3 months].
his second ability is called infinite illusions, and it is a ability that can put anyone in an illusion if they look into his eyes while he uses gyo. The third is an enhancer ability where he put all his aura into his fist creating destruction everywhere when used, he called it destruction fist. His last ability is gate of babylon based on Gilgamesh basically he uses manipulation to fire the swords at high speed from his personal space by creating a portal, it's a further application of his kamui and teleportation abilities. Also during this one year he manged to further increase his weight to 150 kg, making his body that is much stronger than Ubo however he still need a little bit more to go before he has the same body strength as Merium the chimera ant.
