Glad we didn't get to wait another episode to understand what Shou ment last week. His parents led the gas attack in Tokyo back in 1995 and that killed Momoka.
Listening to Takuki's speech, I'm guessing he never completely healed from that accident. He is probably seeking revenge. By mean of Momoka's diary? Possibly. I'm also guessing Yuri (who get half of the diary back in episode 10) has paired with him with the same goal. She must have lost someone dear in the attack too...
Now, I certainly didn't expected Himari to die ;__;. Not supporting KanbaxHimari one bit, but I did feel sorry for him when he was trying so hard to revive her. But he isn't the one for her. He isn't his fated one. Hopefully Satenoshi, if he is the one, will bring her back and not simply stand here >_>''.
Fun fact, when Kenzan initiates the attack, code name is Seizon Senryaku :
There is a scene that supposedly takes place before Kenba, Shou and Ringo birth as said on the wagon board. Also station plate indicates that Seizon Senryaku takes place / exists before Unmei no itaru basho (Place of Destiny)
That's confusing @_@ So far most people assumed Place of Destiny was somewhere in the future, the instant of death maybe. But here it's supposed to be before they were even born...
->Time's up for the dude...
Sanetoshi is some kind of Shinigami. If the "Kiga apple" is the sign of life, then this apple is the sign of death.
->And when he comes to visit Himari at the end of the episode...
Doesn't look good :/.
