Satou, can return to earth thanks to the old hero who had a constructuin for satou. Now he can teleport
Yes, Satou can return to "Earth" but it's not the "Earth" that Satou came from. After introducing myself, I told her the same thing I said earlier. "Don't you know that our son went missing 10 years ago?" "10 years ago? He left me a business card though--" I hold out a business card that Satou gave me. "I think you're mistaking him with someone else. That child went missing when he was attending an university. He shouldn't be working anywhere." I recalled, the words "The world might be different" that Satou said when I listened to her. After apologizing to her for the clamor, I left the Suzuki house.
