Sonic Underground Series x Older Sister! Princess! Oc Insert

Join Sonic the Hedgehog, his triplet siblings, Sonia and Manic, and their eldest sister, Sophia, as they journey all throughout Mobius in search of their missing mother and former ruler of Mobius, Queen Aleena.

Along the way, they will need to evade capture from the evil Dr. Robotnik and his lackeys, who wish to stop the royal siblings from finding the queen and fulfilling a prophecy that leads to Robotnik's downfall.

Together, they use their mystical and powerful medallions, giving to them by the Oracle of Delphius, that transform into musical instruments, as weapons to, not only fight off their enemies, but also as instruments for their underground rock band called, "Sonic Underground".
