Silvia

She met Shiro when she joined her party for the Spider's Whisper Raid.

Background
At first she didn't want to join Shiro's Party cause she felt the responsibility of looking after Jonas' Party in place of her father, who was originally part of the time but died. However after a Dungeon Mutation leaving two of Jonas's Party members dead, one traumatized and one retiring, so was without a party. But due to the two deaths having something in common, Shiro, she was a bit to join  Shiro's Party, until she bumped into Lyrica Valenstaine and Madison on their way the dungeon Ocean Sky Fortress (chapter 133). After the dungeon she decided to join them, the other girls and her meet Shiro and she was accepted into the party (chapter 143).

Appearance
Beautiful

After Class Up
Her appearance had changed slightly as her hair shifted to a turquoise colour that was mixed with white. Her features had been refined while her bosom stayed the same, thankfully. Opening her eyes, the group could see a pair of beautiful golden irises that looked back at them.
