Talent
Lv. 1
When Slashed Dream reaches 9 point(s), the Ultimate can be activated. During the Ultimate, reduces enemies' Toughness regardless of Weakness Types and reduces all enemies' All-Type RES by 10%, lasting until the end of the Ultimate.
When any unit inflicts debuffs on an enemy target while using their ability, Acheron gains 1 point of Slashed Dream and inflicts 1 stack of Crimson Knot on the target. If debuffs are inflicted on multiple targets, then the 1 stack of Crimson Knot will be inflicted on the enemy target with the most Crimson Knot stacks. This effect can only trigger once per every ability usage.
After an enemy target exits the field or gets defeated by any unit while Acheron is on the field, their Crimson Knot stacks will be transferred to the enemy target with the most Crimson Knot stacks on the whole field.

First Meeting
"Acheron..." Merely a borrowed name. You know my nature, remember my deeds... Thus, I am Acheron.
Greeting
It's raining... {NICKNAME}, care to join me for a walk? Here, I have an umbrella.
Parting
Our journey begins anew. Life passes like a fleeting rain, eventually merging with the ground. May our next encounter be... under a clear sky.
About Self: Movement
Lone voyagers in the cosmos are driven by two desires: to tread in the trails of the past, and to forge their own way. But under THEIR scrutiny... most end up adhering to the former.
About Self: Habits
In the hazy memories of my distant hometown, there were often heavy thunderstorms. Fearing their makeup would be ruined by the rain, girls carried makeup with them wherever they went. I have no reason to do so anymore, but the habit still remains.
About Self: Identity
Dreams, in essence, are meaningless. Their purpose is painted by the backdrop of life. Yet, if that backdrop is "emptiness"... then dreams are reduced to colorless, hollow shells.
Chat: Rain
As the raindrops tumble from the crimson leaves, their pitter-patter on my umbrella whispers gently to me. In these moments... I find brief serenity.
Chat: Weapon
If one carries a blade, it's bound to be used to cut something down. My reason for drawing my sword — past, present, or future — remains singular.
Hobbies: Peaches
They embody life's delights and pleasures, but are equally fragile and short-lived... Such regret is inevitable, so let it be.
Annoyances
When I awoke from that place, the sea's horizon still held faint thunder, and the falling blood rain was easing — the sight of that moment lay strikingly clear before me.
Annoyances
When I awoke from that place, the sea's horizon still held faint thunder, and the falling blood rain was easing — the sight of that moment lay strikingly clear before me. All other memories, both prior and subsequent, paled and slowly ebbed away.
Something to Share: Weapon
Curious about this blade? When unsheathed, it unveils the memories stored within — every instance I've swung it, in the beginning, the end... and nothingness.
Knowledge: Black Holes
Black holes aren't spectacular, nor are they fierce. They're silent, like a lone, forlorn gaze watching over you and me... and then gently they consume everything, bestowing a frigid, silent embrace.
Knowledge: Paths
Seeking knowledge, craving revelation, striving to exist... humans traverse the path of fate.

Humans traverse the path of fate... seeking knowledge, craving revelation, striving to exist...
About {NICKNAME}
I, too, was once kept in someone's heart like you. Those trivial moments, when looked back upon, are worth more than a thousand words... The past shapes who we are today. Some things are hard to remember, others hard to forget.
About Firefly
In her, I see the fireflies of the forest, dazzling and bewitching, yet shining only for a brief moment.
About Black Swan
A lady of elegance and dignity, her benevolent offer lingers in my memory. That dance... it brought me a sense of warmth and nostalgia.
About Aventurine
A shattered emptiness draped in the guise of desire... his existence is strikingly powerful, yet the self beneath is extraordinarily faint.
About Welt
There are many types of people called "heroes," and he is among the most genuine... I have seen many such people come and go.
About Sam
Wherever the fiery giant treads, scorched earth follows. Yet, it's those consumed by unending fire... who, after the flames vanish, quietly hold the ashes in their lonesome embrace.
Eidolon Activation
"To cross the same river twice" ...Hardly a hardship.
Character Ascension
Never turn back — the path behind is gone.
Max Level Reached
The distant vistas are hazy... but must surely hold beauty.
Trace Activation
Another blank canvas.
Added to Team With {NICKNAME}
So it's you... Our time spent with one another is precious.
Added to Team With Black Swan
Our paths cross once more... Ready for another dance, Memokeeper?
Added to Team With Aventurine
All or nothing... time will tell.
Added to Team With Welt
Even before the abyss of a black hole... we still have a choice.
Battle Begins: Weakness Break
Half the work is already done.
Battle Begins: Danger Alert
This is where it ends.
Turn Begins 1
Did you come here of your own volition, or was it fate?
Turn Begins 2
Another journey begins.
Turn Idling
Hasten — we've hardly any time left to say farewell.
Basic ATK
Where are you going?
Skill 1
Existence is fleeting as the dawn's dew, destined for oblivion.
Skill 2
On the still waters of oblivion, I guide the wandering souls.
Hit by Light Attack
Again?
Hit by Heavy Attack
How familiar...
Ultimate: Activate
I weep for the departed...
Ultimate: Unleash
Dusk's rain... it too shall fall.
Downed
All will eventually rest upon the earth...
Return to Battle
I'll stay with you a little longer.
Health Recovery
Don't worry, it's just a scrape.
Technique
Stream forth... the gleam of old blades.
Battle Won
Another blood debt repaid.
Treasure Opening 1
Seek, and you will find.
Treasure Opening 2
Don't forget to let your friends in on the action.
Precious Treasure Opening
This is what exploring the cosmos is all about.
Successful Puzzle-Solving 1
Life is a puzzle in and of itself.
Successful Puzzle-Solving 2
Perhaps there's more than one right answer.
Enemy Target Found
Storm's on the horizon.
Returning to Town
This haven of memories, every touch, every moment is like a thorned rose...
