His thinking is similar to Cao Cao, Cao Cao also often uses tactics like this to recruit enemy generals & in the end he succeeded in controlling China.
love it. finally there is a manga artist who dares to turn China into a terrorist.
There have been many stories and films that have turned the Arab, American, Russian and North Korean countries as terrorists.
therefore it becomes a little boring, because the terrorists are from that country only.
I have 2 theories:
1. Kyoukai was killed by Rei in order to save his soul and so that Rei could replace Kyoukai in the Hi shin unit. Because kyoukai can't be saved anymore.
2. Rei is defeated by Kyoukai and he saves Kyoukai by giving his life using a forbidden technique.
Any other opinions...
