Theo is going to another department of the army, and he might just work under Annette! I don’t think Theo’s role will be demoted in Volume 11. He’s an Eighty-Six after all. I think the author may even try promoting his plot line so that she can explore another department that is helping with the battle. And currently, Annette is still playing a part in the battle and leads her own experiments, but because she isn’t a main character, we still don’t know what’s going on out there, so the author might just use Theo to explore her area.
Ah,I see. For me the series has two protagonist Its Lena and Shinei. The other 86 guys are for me are either just one of the main characters or main supporting characters. But in my opinion the series has dual protagonist,Its Lena and Shinei.
