/And now the 4th chapter, hope you like it. By the way, if there is a shipping here that isn't mentioned at Sonic Rainbow Generations it is because, like I said, they work independetly. If you want to say Sonic Rainbow Generations is a parallel timeline where Sonic doesn't date Rias and the gang, or if you want to say that this story is a timeline where Sonic dates Rias and stuff, both are correct. These stories, even if for me collide in the same timeline, are made for different public, so they could be different timelines. /

Chapter 4: flight at the skies part 1

Once the explanation was over, Rias had to reaffirm some things "Let's see...the world is divided in 7 parts and for knowing a better way to fix this situation is going with the Professor Pickle right little fella?" She said to Tails as this one nods kindly. "Understood. We'll go in the morning, get all energies you can" Rias said as she walks upstairs calmly. "Ara-ara, ufuf let's go to sleep Koneko-san" Akeno said with her normal tone. Koneko simply shrugged and walked to her room. "I'll sleep here Sonic!" Tails said. "You sure buddy?" The hedgehog asked. "Yeah don't worry" Chip looked at Sonic "If you want I can sleep with him" Sonic smiled and nod. He went upstairs to sleep down. "Sonic? Mind if we take a bath together?" Rias asked as she was at the entrance of the bathroom. Sonic shrugs and walks to her calmly.

Rias fixed the water of the bath to make it comfy for both. Sonic simply entered and relaxed as Rias does as well. "Sonic...I want to give you something" She says as she pokes Sonic's chess, transforming him into a human. "WHAT?!" Sonic asked shocked as he is nervous. Rias kissed his lips again to calm him down "It's ok Sonic. I am here. You're quite handsome like this" Sonic blushed. He didn't know what to do. He felt free for some reason. Rias smiled a bit as she relaxed. Her big breasts were wet and exposed "I am sorry Sonic" Rias said. "I...well, we just met jeje" She said nervously. Sonic didn't say a word as he knew where does this was going. Sonic shrugged, kissed Rias lips and continue with this strange favor he was doing to Rias...just a payback for saving his life.

At the morning, Tails, Sonic, Koneko and Chip are on the Tornado. Asia is as well. Rias and Akeno are flying. They are going right now to Spagonia where the professor would be. "JAJAJAJAJAJA" Raynare came flying as Eggman's ships come again. "Looks like we got company Tails!" Sonic said smiling at this situation. Tails nods and transforms the tornado into it's battle mode. "I won't let you hurt Sonic-kun" Akeno said as she attacks Eggman's robots with her lightnings. Rias uses her dark powers doing the same. The robots begin to throw lots of lasers at point blank range. Raynare attacks Rias with some of her forces as this one blocks. "Sonic...I'll protect you!" Rias said to herself as the hedgehog kicked Raynare out of the way and lands on Tails' tornado. "Jejeje pretty cool" Sonic admitted. Koneko and Asia can't do anything, just watch and hope for Tails to protect them.

Finally, the ships got destroyed by Rias and her group. Sonic was smiling and winked at Rias, this one simply blushed "Baka..."she said nervous for keeping herself of what they did last night. She loved Sonic by now. Akeno is planning to do her move, just she wants to take her time for not screwing it up. "I think Sonic has a big issue..." Chip admitted and Tails nodded.

Eggman wouldn't give up and showed a mech: the egg emperor. "Give it up!" Sonic said. "Hmph enough of this! Sonic, Tails, everyone! Time to meet your maker!" Eggman was going serious with this machine. Sonic grabbed a staff and jumped to the floor. He broke the staff and runs on an artificial path, similar to the ones seen in Starlight Carnival. The Egg emperor dashes at the hedgehog to end this. Sonic dodged his move barely and kicked the egghead's mech weakpoint. "Jaja come on Eggman, can't you keep up?!" Sonic said as some sort of lightning gets through the egg emperor and made him crash against the ship. Eggman managed to survive.

"What the?!" Sonic said as someone was flying in front of him. "Sonic the hedgehog, for orders of Odin, my mission is defeating you!" A white haired girl with big attributes said seriously.

Sonic runs again using his artificial ways as the enemy is chasing him. "A Valkirie" Rias said. She is tied of hands. Her brother would have great issues with Odin if she fights. Sonic managed to dodge an attack coming from this enemy and kicked her. "Hey come on! Who's Odin?!" Sonic groaned in anger...
