i recently talked to Aika Thanka where she askes you to find her two missing sisters the first line of the quest objectives asks you to find the strongest brawler in Amagal but i'm unable to find this brawler so i'm unable to progress the quest does anyone know where this Brawler is so i can find Bennika Thanka and progress the quest apologies if this is already an open topic already i was unable to find any mention of this quest or topic on google or through out the walkthrough guide in addition to an actual list of the vanguard squad leaders other than bits and pieces but nothing that definitively tells you who your looking for and what quests you need to do to unlock them i'm assuming that Aika Thanka is the missing vanguard squad leader i'm missing  i could be wrong but as stated I've yet to find any physical list separating vanguard squad leaders from side characters and the main characters and i've hit a wall in progression of the "Brutal Oni Sisters" quest so i cant confirm if they're the missing squad leader i'm looking for or if my game is just bugged or if i've hit the wall of unreleased content until next update.

Vanguard Squad Leaders I've been able to confirmed so far list:
1. Jessy, 2. Worilla, 3. Fang, 4. Magdalene, 5. Ailluin, 6. Bristol, 7. Lili, 8.  Kurohime,  9.  Alcena, 10. Wendy, 11. Frall, 12. Phyrra, 13. Owen, 14. Mia, 15. Leneth, 16. Unreleased Character, 17. (Idk this character's name yet), 18. Unreleased Character,  19. Della,  20. Scruffy.

If anyone knows the quest for each vanguard leaders name please  put the quest by the vanguard leaders name for newbies like me as a minor guide that is i need of actual making thank you for your help with the Vanguard squad leader listings for newbies like me.
