Zongman: People in Chaldea, all the group members are wives

Traveling through the world of Soman, Lin Yi joins Chaldea with his childhood sweetheart Fujimaru Ritsuka.
I thought I would have to cling to Ritsuka's thighs, but I didn't expect to join the girls' mutual aid skirt and awaken the Heroic Spirit Simulator!
In the Age of Greek Gods, you completed the Twelve Divine Trials with your weak body and shot down a wandering planet with your mortal strength!
You are the one that all gods love, and you are also the white moonlight that Athena regrets but can never touch again!
In the world of collapse, you are the "experimental product" picked up by Mobius, containing the genes of thousands of collapse beasts, fighting on the moon, and finally closing your eyes in the arms of Alicia...
At the Fuyuki Holy Grail War singularity, Lin Yi broke out in a cold sweat as he looked at the extremely familiar faces.
"Why are you here?!"
Athena: "If you don't come, you will be snatched away by a vixen!"
Alicia: "This time, I won't let you leave!"
Fulilian: "You are my hero, and only my hero!"
Tiamat: "My child, come back to my arms as you did before!"
