A strikingly tall and busty beauty with orange hair and a small dwarf with white hair are walking side by side through an amusement park.
"So, Captain, what are we going to do first?", Rangiku asked and looked at which attraction she might like. "How about that?", She pointed to a water rollercoaster that made you get pretty wet. "No thanks, I can do without that.", Toshirou grumbled back and crossed his arms over his chest. "But, but Captain, we should have a nice day!", Rangiku glared at him expectantly. "Pfuuu", the white-haired boy let go of annoyance and then said: "If I have to spend my day off with you in an amusement park, then at least we can ride it!", His gaze was directed at the giant rollercoaster of the park. Rangiku's eyes widened: "Captain, this is ...", she seemed speechless for a moment, but then, "... the biggest and fastest roller coaster in this park."The joy was written on her face because she was enthusiastic about the idea. They lined up and as they were about to get in a" stewardess "came to them." Sorry, but didn't you see the sign? ", she looked down at Toshirou disappointed," I'm really very sorry, but children under 1.40 m are not allowed to ride.[oO
