All that is past has returned to Nihility. Just like tears, eventually disappear in the rain.
Don't look back. There is nowhere to go but forward.

Overview
A drifter claiming to be a Galaxy Ranger. Her true name is unknown, and she walks the cosmos alone, carrying with her a long sword.
Though aloof and taciturn, her blade flicks out like lashing lightning. And yet, she always strikes with her scabbard, never drawing the sword free.
Abilities
- Basic ATK: Trilateral Wiltcross
Where are you going?
Deals Lightning Damage equal to 50%—110% of Acheron's ATK to a target enemy.
- Skill: Octobolt Flash
Existence is fleeting as the dawn's dew, destined for oblivion.
On the still waters of oblivion, I guide the wandering souls.
When using her Skill, Acheron gains 1 point of "Slashed Dream", then inflicts 1 stack of "Crimson Knot" on a single target and deals Lightning Damage equal to 80%—176% of Acheron's ATK to this target, also dealing Lightning Damage equal to 30%—66% of Acheron's ATK to adjacent targets.
- Ultimate: Slashed Dream Cries in Red
I weep for the departed...
Dusk's rain... it too shall fall.
Acheron will unleash "Rainblade" 3 times and "Stygian Resurge" 1 time, dealing Lightning Damage equal to a maximum of 223%-372% of Acheron's ATK to a single target enemy, and dealing Lightning Damage equal to a maximum of 180%-300% of Acheron's ATK to other enemies.
| Rainblade | Deals Lightning Damage equal to 14.4%-24.0% of Acheron's ATK to a single target enemy, and removes up to 3 stacks of "Crimson Knot" from that enemy. When "Crimson Knot" is removed, deals Lightning Damage equal to 9.0%-15.0% of Acheron's ATK to all enemies. The damage multiplier increases for each stack of "Crimson Knot" removed, up to a maximum of +36%-60%. |

| Stygian Resurge | Deals 72% to 120% of Acheron's ATK as Lightning Damage to all enemies and clears all "Crimson Knots". During the Ultimate, "Crimson Knot" cannot be applied to enemies. |
- Talent: Atop Rainleaf Hangs Oneness
After reaching 9 points of "Slashed Dream", Acheron can use her Ultimate.
When using her Ultimate, Acheron can reduce enemy Toughness while ignoring Weakness types and decrease All-Type Resistance for all enemies by 10%—22%. When any unit inflicts debuffs on an enemy target while using their ability, Acheron gains 1 "Slashed Dream" and the enemy gains 1 stack of "Crimson Knot".
When an enemy target with "Crimson Knot" is defeated, that "Crimson Knot" will be transferred to the enemy unit with the most "Crimson Knot" stacks on the field.
- Technique: Quadrivalent Ascendance
Stream forth... the gleam of old blades.
Attacks the enemy and enter the battle. At the start of each wave, she gains 1 point of "Slashed Dream" after her next Ultimate and gains 1 stack of "Crimson Knot" on a random enemy, inflicts Lightning Damage on all enemies based on her ATK and reduces Toughness of all enemies regardless of Weakness Type.
If Acheron encounters a Normal Enemy, her Technique will vanquish it without even entering battle. And if the hit doesn't land, it won't consume any Technique Points.

About Other Characters
This part is about what Acheron thinks about the other characters in Honkai: Star Rail.
A lady of elegance and dignity, her benevolent offer lingers in my memory. That dance... it brought me a sense of warmth and nostalgia.
A shattered emptiness draped in the guise of desire... his existence is strikingly powerful, yet the self beneath is extraordinarily faint.
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.
In her, I see the fireflies of the forest, dazzling and bewitching, yet shining only for a brief moment.
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.
There are many types of people called "heroes," and he is among the most genuine... I have seen many such people come and go.
