That's Captain with her long hairs.
Actually it's 10, not 9. The rest is correct.
Now I'll call the total level of your team Unit Skill by point, each 10 Points you get 1 Team Unit Skill Level. Your team always start with 10 Points (even if it's empty), and when you put an Idol with Unit Skill Lv10, it's 10+10=20 Points, so you'll have Team Unit Skill Lv2. If all your Team members (9 girls) have Unit Skill Lv10, you'll have 10+90=100 Points (Team Unit Skill Lv10). That's why if all your Idol have Unit Skill Lv5, then it's 10+45=55 Points (Team Unit Skill Lv5).
