It’s a story of him entering the tower by following his memory.
When Zero came to senses, he realizes that he is in a cave.
Arriving in the front of the tower by depending on the word that is ringing in his mind,
he goes into the tower after meeting the spirit ‘El.’
In the tower, he can only do battles based on ‘Rock-Paper-Scissors’
by the rule of the spirit El.
Please solve the reason why Zero came to the tower by defeating the enemy
with ‘Rock-Paper-Scissors’ and ‘Cham cham cham.’… View full description on the official store →
