You're saying No to my second point, right? If so, then thanks for explaining. The point I was saying there though, was that the kids are being used as bait all the time and it's getting repetitive. The part about me saying i wonder how easier life would be is just my frustration with the repeated abductions. I know they're very clearly playing a crucial part in Rai's return.
I'm on ch 287 right now and i'm seeing a lot of repetition.
1. The other guys who aren't as strong gets involved with the enemies, can't win the fight, then Frankenstein shows up to save the day. When he's expended his energy, either already defeated an enemy or is having trouble, Rai will then step in last minute and finish the job. The fight scenes are epic but it's the same formula for every fight so it gets predictable. Regardless of how the fights start, it always Frankenstein then Rai.
2. The kids are used as bait. All the time. I like that Rai and the rest are favoring these normal humans and forming friendships but at the same time, they're a hindrance and I wonder how easier life would have been if they'd never got friendly with anyone.
