Ar Nosurge: Ode to an Unborn Star

The player controls a party of characters named Delta and Casty at the start, with the ability to switch freely between two pairs of characters later in the game. The gameplay involves turn-based battles where the male character attacks enemies while the female character charges up her magic. The player must defeat as many waves of enemies as possible within a limited number of turns.

Other features include Genometrics, a visual novel-like segment that explores the subconscious mind of a chosen character, and the ability to equip crystals during Purification Ceremonies to enhance party members' fighting abilities.
