Anyways the second goat of this volume is Lyno, I really hope that Aneko Yusagi doesnt reintroduce Medea now that the enemy has recovered Malty's soul.
On to S'yne sister, I always thought that a certain person that will appear in volume 20 was S'yne's sister so I was actually surprised to learn that the blond girl is her sister.
I only look at color pages after it's finished so I never knew.
