The Poisonous Fangs Approach! The Second Ruins Surrounded by Intrigue! - S1.E15

The episode begins with our heroes walking through the woods as we find they are looking for the Earth Cosmo Core. Haruto appears, informing them that there is a town in front of them and a visitor behind them before he disappears once more, despite them asking him to stay. The "visitor" turns out to be Ichi, the older Saint from Palestra that was never able to use his powers correctly, and since that time the bronze saints found some surprises along the way.
