After seen the girls fight at the tavern the night before (you can see that here : https://www.renderosity.com/mod/gallery/the-tavern-fight/2801423/?p), Romatzo the Dwarf is eager to team with them. So the day after, before the three girls leave the town, he ask them if he can join the group. At first Marina, Delphine and Minalva wasn't sure to wanted him in the group, but his sincere and naive smile convinced them to give him a try. And having another warrior in the group furthermore one with arms as big as tree trunks could be useful. It's funny how some character can take control of you, because when I have add Romatzo in the scene of the tavern fight, he wasn't supposed to join them after. But he loved their attitudes and really wanted to join the group. So I had to do it. :D
