A female Newman and GUARDIANS instructor. She is assigned to oversee the training of Ethan and Hyuga when they enter the GUARDIANS. Strangely for a Newman, she is unable to use [=TECHNICs=].

Lou's specialties include data gathering and analysis, hacking, and [[ThereIsNoKillLikeOverkill blowing stuff to smithereens]] with her [[{{BFG}} SUV]] [[KillSat weapons]].[[spoiler: Lou is a special CAST in that she is the only CAST to have multiple bodies that all share the same mind - an ability previously only belonging to Copy-[=CASTs=]]].

A senior Beast instructor within the GUARDIANS. Laia is renowned for her ruthless training regimen, to the point where merely graduating from her tutelage is considered an achievement in itself.

When Dallgun is killed during the events of ''Ambition'', Laia inherits his position as leader of the GUARDIANS, although she is reluctant to do so at first]].
