Hi Scoool! Seha Girl - 1x07 - エッグマンvsソニック with セガ・ハード・ガールズ- Followmy.tv

The girls team up with Sonic to chase after Eggman through various dimensional warp zones, briefly passing through Sonic the Hedgehog and Sonic Adventure. Luckily, upon returning to Border Break, the girls manage to retrieve Mega Drive's encyclopedia and give Sonic an invincibility power up to defeat Eggman and stop the hacking, also destroying the enemy core and passing the exam in the process. The girls leave the game and, after nearly having Center's true identity revealed, receive 25 medals each.
