Mindscape Cinema

Each Mindscape awakening requires Agent Focus: Billy ×1.

01

Dazzling Entrance

"You guys are way too honest to be bad guys!"
"All lined up, like NPCs at the shooting range!"

When Billy hits an enemy with a Dash Attack or Dodge Counter, he gains an additional 2.7 Energy. Can trigger once every 5s.

02

Roaming Gunslinger

"The Starlight Knights never run from danger. That's what we call tactical repositioning for better aim!"
— User "Dreamgirl Monica" from the Starlight Radiance messageboards.

Billy's Dodge Counter DMG increases by 25%.
Rolling Shots during his Basic Attacks are treated as dodges, making Billy Invulnerable during the skill and able to trigger Perfect Dodges.
When a Rolling Shot triggers a Perfect Dodge, it will automatically become a Dodge Counter.

03

Teachings of the Starlight Knights

Never neglect your training, and never stop improving! This is the philosophy of the Starlight Knights. Billy believes in it wholeheartedly, and practices it sincerely.

Basic Attack, Dodge, Special Attack, and Chain Attack Lv. +2

04

Starlight Ballistics

These explosive bullets of Billy's own invention are incredibly lethal at close range.
Their performance far outstrips Billy's original intention of simply making them cooler.

When Billy hits an enemy with his EX Special Attack, the skill's CRIT Rate is increased based on the distance from the enemy. The closer he is to the target, the greater the effect, up to a maximum increase of 32%.

05

Lost Technological Constructs

Unknown precision components and unique structural design have given Billy performance far beyond his peers... And maintenance costs far beyond his means.

Basic Attack, Dodge, Special Attack, and Chain Attack Lv. +2

06

Starlight Hero

"Hooboy~ Feelin' great! Move aside, Anby, it's my time to shine!"
"Yo, Anby — can you play the Starlight Knight theme?"
—excerpt from Cunning Hares' "Top 10 Forbidden Sentences," selected by Anby

When Billy accumulates 10 hits on enemies or triggers a Perfect Dodge, his DMG increases by 6%, stacking up to 5 times and lasting until he's knocked back or launched by an attack.
