Marical is a Color C (like Luluce) and has a small body type without any letter so far - All I can find is that it might be a "W" body (SIS-W00) - Regardless the torso is small with a small bust.
Aesthetics:
Overall the body has fantasy elements with 'tech' style plates.
Marical herself seems to be an adult or young adult, with pale blonde twin braids and an obvious mage or wizard aesthetic.
While there are bare hips, the legs and arms below the upper rings can be used on anything else as only the hips and shoulders have skin.
Mechanics:
The body is from early 2026 with good articulation.
One of the hands have a 3mm peg that is meant to be used with her tome, but you can stick other things onto it.
Equipment:
1 Wizard Hat that sticks into the middle part of the hair - Fits over round hair styles
1 Cat Staff
1 Spell Tome - Can be opened, has five 3mm holes on the back
3 Face plates - Smiling, angry yelling with teeth, surprised open mouth with teeth
2 pegs to replace the two giant hair beads so the hair tufts plug into the braids
7 Hands - 2 holding, 2 fists, 2 dainty spread open hands (teehee), 1 hand with peg
Various white ring parts and flat white soles (old style)
Various extra parts:
Extra thighs without ball joints - You can replace them using the old style grey ball polycaps, but you need to shave them down to fit them.
There are skin parts that seem odd - They are the same type that Color B Shuremi uses, but it's nowhere near enough to replace all of her skin.
A couple of extra joints.
Conclusion:
A lot of 30MS kits are cute, but they also look generic.
Marical's model has a little more personality to it and a visually recognizable aesthetic - It looks mostly fantasy and the more angular parts and the neon green baubles are a bit more techy, if you look closer.
You can obviously use the staff and hat with other 30MS kits, while the book require being held or the included peg hand.
You can use the circular 'spell' effect from the Witchcraft Weapon set and put it between the hand and the book to do a 'spell action pose'.
