It was the next day and Rias along with Koneko woke up and saw Sonic wasn't in bed which got the nervous as Rias looked out the window to see Sonic looking at the clouds that are blocking the sun and while they quickly got dressed and rushed out to him "SONIC/BIG BRO!" they called out as he turned around and got tackled to the ground "girls? What's wrong?" he asked "Sonic why are you up so early?" Rias asked "I woke up with a power that I sensed it felt different and yet kinda similar to mine the pain, rage and self-loathing. Something is like me and it's power in building" he told them "good or bad bro?" Koneko asked "I....I don't know" he told them after that they headed back inside and Sonic made breakfast however while they were done getting dressed for School before a Gremory portal appeared.

Before Rias Brother. Sirzechs appeared "brother, what do I owe this visit?" Rias asked "it's not a visit sister, I need Sonic, there is a creature that's power is like your own Dark form" he said which shocked Rias and Koneko from what Sonic told them this morning "so where is it?" Sonic asked "we sealed it in a barrier but while inside seconds is like hours their, we did it to stop it from going on a rampage" Sirzechs told them "that explains why I felt it's power before it suddenly just disappeared" Sonic said to himself "Sonic, this something I am request help us kill it or just get it to calm down so it won't attack the underworld" Sirzechs requested "alright" Sonic replied "WHAT?!" Rias and Koneko shouted "Rias, sis. I'm the only one that can stop it and understand it. Beside we got enough to worry about with Kiba and the sacred swords along with the two church girls, sis I need to find and help Kiba, but Issei does join just kick him in all men's weak spots" he said with a smirk making Koneko nod and smile as he turned to Rias who looked nervous "Rias, I promise once I'm done with this creature I will come back and stay by your side, so Don't worry. I promise I'll be as quick as I can" Sonic said as she hugged him "I know but just promise me you'll be careful" she told him as he smiled "I do one better, I promise when I return stay with you for the rest of day and give a kiss okay?" He offered as Rias' smile "you better keep that Promise" she said "I will" he replied before he turned to Sirzechs as the two stood under a portal before being teleported away as Rias and Koneko nodded and left to continue the day.
When Sonic and Sirzechs appeared he saw a barrier around a frost "alright you want me to either kill it or just tell it to calm down?" Sonic asked as Sirzechs nodded "what is the creature?" Sonic asked "a black dragon" Sirzechs replied "a dragon....? Like Ddraig?" Sonic questioned "yes but she is different, Sonic she has been through hell and no one could understand that she had no choice but to kill her family to survive as they went mad and want others to know her pain but she has been lying dormant for so long that her power has grown it also rivals...." he stopped himself "who? Who does she rival?" Sonic asked "sorry but please don't ask" Sirzechs replied "....alright just let me know if something happens with Rias when I get back out. Okay?" he asked as Sirzechs smiled and nodded before he opened a gap and Sonic stepped through before it closed behind him. Sonic walked through the the frost and didn't see or feel anything but he felt his arms shaking *Ddraig I can't sense this dragon, do you have any Idea where she is?* Sonic asked him dragon partner "Sonic, that's why Sirzechs sent you in cause you are like her, he means you have a form that can find her, just turn and let it guide you" Ddraig replied as Sonic understood what he meant as closed his eyes and opened them to find himself in a chair a dark room "I thinks it time for a little brother and brother bonding wouldn't you agree?" as Sonic closed his eyes again allowed his memories and rage to flow through him as he turned dark but his eyes reminded the same as felt the darkness of the dragon as he closer and closer saw a cave however he could only see darkness but before he could enter he quickly jumped back to avoid a tail attack as his dark form was gone before he looked back and saw two eyes looking at him before the darkness was moving and revealed itself.
