User blog comment:AquilaeAltair/OnS Theories. Fourteenth Theory - Shiho Kimizuki. A traitor or a person who understands the situation the whole squad is in./@comment-36009152-20190830230555

Update as of Chapter 81 Kimizuki may have gone drastically full traitor by kind of legging it over to Saito's (of all people?!) side!

On one hand a good kind of 'traitor' he is ditching the army with what they were using Mirai for and he has reclaimed her properly. We don't exactly know who he is betraying by accepting Saito's offer and presumably making his way to Shinjuku to join his allies.

Is kind of bad that he and Yoichi have left Shinoa (debatable if they can see her, or if it's just us the readers who can view Shinoa and the characters are seeing something else). More so if they do not find Mitsuba on the way, or anyone else from the squad.

Then again it is a war zone currently so Kimizuki can't be blamed for taking his sister and running, the others can catch up. So long as they are okay, then if it's deemed betrayal but no ones hurt, all good!
