Return Ace

Your bullet is my bullet! It's up to you to avoid it, such as being hit. A unique rule-reversing Shmup "Return Ace" that hits the enemy's army and boss with a barrage from the front. By the time he woke up, the situation had already been decided. He was given neither more power nor a sturdy body. It is the "power to return" everything. The battle began, guided by someone's voice, without even determining his identity and desires.
