Michella Watch (ミシェーラ・ウォッチ, Mishēra Wocchi) is the younger sister of Leo. She is unable to walk since birth. When visiting Jerusalem's Lot with her family, she lost her eyesight in order to let Leo keep his.
Michella is a young girl who appears around teenage. She has long brown hair tied up in a black ribbon and wears a warm jacket and gloves, a lap blanket over a green dress, and brown boots, however in Volume 10 she uses different clothes. She sits in a wheelchair as a result of her inability to walk.
Michella cares greatly for her brother,having a big bond since they were kids, often calling him her tortoise knight. Also she is very brave allowing her own eyesight to be taken in exchange for her brother to gain sight.
According to Leonardo, she can sometimes get very childish and easily moody.
Michella Watch is Leo's younger sister who has been paralyzed since birth. Her parents took her on a trip one day to the borders of Jerusalem's Lot in secret hopes that something strange would happen to give her back the use of her legs.
Much to their dismay a giant being of unknown origin (Riga El Menuhyut) appeared and offered her and her brother a choice, that one of them needed to sacrifice their eyesight in order for the other one to see. Leo, paralyzed in fear of the giant being, said nothing while Michella bravely made the decision to sacrifice her eyesight in order to save Leo. She is now blind though her whereabouts remain a mystery, but it is implied in the end of the anime that she is with a man near to the mountains, where she and Leo visited one day, before the series.
She reappears in volume 10 when she calls Leo and visits him in Jerusalem's Lot to announce her engagement with Toby Mcaughlin.
