Alex (アレックス Arekkusu?) is a horse belonging to Carissa, introduced in Shinyaku Toaru Majutsu no Index.[1][2]


Alex is described as a muscular horse, fully outfitted with reins and armor.[1]


According to the female knight, Alex is apparently known for only growing attached to pure maidens, though not to the extent of unicorns in legend.[2]


Alex was raised as a royal horse, belonging the Second Princess Carissa. While Carissa was imprisoned, she ordered the Female Knight to take care of Alex. He normally only got to walk around the Tower of London's courtyard.[2]

Alex was trained as a military horse, with several different spells used in the process of raising him for official duties, such that running around a 2km lawn won't be enough to exhaust him. He is also equipped with special rubber horseshoes for urban terrain and his mobility rivals that of a motorcycle.[2][8]
