Rias's Knight

A Discovery {S3 Ep 12}

This is in Season 3 episode 12

After issei defeats the evil dragon in the dimensional gap with Rias they fell into the vortex , they find a floating figure cloaked in red and black aura . Rias recognized the figure and rushed to its side , she pulled it closer as Issei came to her side , he gasped as Rias began to cry . The figure that laid in the magic was none another than Jin , in a near death state with his wounds still visble yet he still lived.  His chest raised and fell with every breath , Rias held jin close " my brother...he is alive!" She weeped , Issei wiped tears away " Jin!". Suddenly a slit in the dimension appeared as DD , Great Red Dragon flew by and opened another slit for the three devils to return home . They appeared on a beach , jin was still surrounded by aura as Rias and Issei shared their first kiss.
They were teleported home and seemed confused as their memory were fuzzy  Rias frowned having a odd feeling she opened a magic circle and Jins form appeared in the magic . The entire group gasped as Koneko and Akeno covered their mouths as tears kept falling " Jin..."
Kiba's eyes were wide " how ..whats this magic ?"
???:" Its my magic"
The ORC group turned to the voice and saw Ophis , she smiled and made the unconscious boy float towards her " This young boy has more potential than anyone believed ,I had my magic protect him and teleport him into the dimensional gap where he can live on , to be honest I wanted to leave him in the dimensional gap until I needed him " Rias was  pissed " what do you plan on doing with my brother ?!" Ophis smirked " you really know nothing Rias , your younger brother has a very rare sacred gear and you never realized it"
Issei:" a sacred gear?"
Ophis :" it is called Scarlet Flame , the user's one eye turns gold when it is used , it is awfully mistaken as normal magic however this sacred gear is wired with emotions , it becomes more powerful with each emotion . with the proper training this boy can be a perfect weapon, not to mention his destruction magic he still needs to unlock "
Rias looked down :" Scarlet flame.."
Issei growled :" Give Jin back!"

Orphis  looked at Jin " mm seems you still have people that care for you young one" she made jin float back to Rias " he will awaken much later ...with memories of his true bloodline " she made the magic disappear around him as Jin fell into Rias's arms .
