A peaceful city. During morning rush hour, the subways were crowded, and at lunchtime, office workers sought out restaurants with smiles on their faces. The snack bar in front of the school always had a long line, and at night, the laughter of children and people out for a stroll never ceased in the park.

But that peace did not last long.

Blackouts that left no record, communication failures of unknown origin, and blind spots not captured by surveillance cameras began to increase one by one, and various villains started to appear in the city.

Villains attacked the citizens and the city, and the people were gradually consumed by fear.

Then, a single ray of hope appeared to push back the darkness.

They were the Eclipse Rangers.

A sentai team based on solar energy. The beings who allowed humanity to achieve the result of "victory" against the darkness for the first time.

The Eclipse Rangers consist of five colors, and the colors represent differences in roles, not a hierarchy.

Each Ranger was strong independently, but they displayed the most perfect combat efficiency when together.

Numerous invasions and monster incidents were resolved by them, and citizens called the Eclipse Rangers the 'Last Heroes'.

Among them was a Ranger responsible for all information on the battlefield.

Yellow Eclipse, Moon Hayul, in charge of situation analysis, energy flow calculation, and predicting villain behavior patterns.

Her combat was always calm. She never let emotions sway her, read the numbers, and always chose the option with the least damage.

The battlefield was within her calculations.
