Melinda Bowen

Melinda Bowen (メリダ ボーウェン, Merida Bōuen) is Shin's guardian, the famous Guru who created magical tools and powerful enchantments. She used to be married to Merlin but due to unknown reason the two split up.

Appearance
Melinda, as Shin described, is an old lady who wears a pair of glasses, a black robe and a pointed hat, and emits the aura of a “Witch.” She has a tall stature, handsome appearance, and has incredibly good sense of style.

Thanks to a magic tool that Shin created based on an exercise machine, Melinda is noted to have an impressive figure even in her 70's.

In her youth, Melinda was noted as very beautiful with a sexy body.

Personality
Melinda often nags Shin when he does something abnormal. She sometimes chokes Merlin whenever it happens as she thinks it was his careless way of teaching magic that brought Shin on to his unique magic. Just like Merlin, whenever it comes to Shin's involvement to Diseum's political deeds, she too snaps. She bursts into tears and gets emotional whenever Shin mentions her as his "grandmother" just as how she wanted him to call her since he was little.

Background
When she was young, Melinda once helped Merlin fight the infamous devil. She later on became Shin's additional instructor. She taught Shin the magic “Enchantment,” which is used to inscribe equipment with magic because this kind of magic was not Merlin's forte.

Chronology
Melinda was seen living with Merlin and helping teach Shin Enchanting Magic. She is later seen having a conversation with Merlin and Michel, about Shin's abnormal abilities and unusual way of thinking that allows him to grow exponentially in magic and martial arts.
