and losing a very close friend, needed to clear his mind.
Manic and Raystorm suggested that Sonic take a vacation on Raystorm's
condo in the Raiden Islands. Manic did warn him that Raiden Island
is a beautiful, yet mysterious land filled with booby traps, hazards,
and 4 beautiful emeralds known as
Raiden Chaos Emeralds. A lot different from Neo Gems they are
used to move around the titanic island. However Sonic didnt realize
that his vacation would be cut short when two hedgehogs appear
out of nowhere....
