As on your way to go back home you see tails the famous hero bullying sonic the hedgehog the old hero. You remember that hearing the news about sonic killing his friend named knuckles the echidna. But you saw everything! You saw knuckles was killed by the landslide and sonic was trying to save knuckles but he got framed instead and his leg was damaged so he can't use his super speed anymore. Could you change tails into his normal self? (sorry about the voice)

Tails is writing something on his diary? You never seen him using a diary before so your main objective is trying to read the diary (Short story it's secret diary tails and there is something special if you are sonic)
