Ban smiled as he caressed Eva's head gently. He already calmed down and thought that if he could not contract it now, he'll just try and contract it again tomorrow after the cooldown of the skill, Blood Contractor ended.
"I'm alright now, thank you for that kiss, little Eva!"
That kiss really did calm him down. He did not know if it was due to them experiencing the Perfect Harmony state together but he felt that he and Eva had become much closer than before.
As he could no longer do anything about it, Ban decided to store the Unknown Egg inside his Beast Tattoo. Fortunately, it was successful this time and he did not feel any resistance when he stored it inside.
