- April the Sunny and December the Cold are complete opposites of each other, excluding their eye and clothing colors. Their ATK and DEF stats are swapped, as well as their skills (April the Sunny: ATK x1.5 / December the Cold: DEF x1.5); April the Sunny is able to control her magic whereas the powers of December the Cold are unstable.
- According to A.I. Sisters December & April's voice, this is to compensate each others' weakness.
