Extradecima

Extradecima, the ojamajo of the week in Cebu, is the most common and sometimes the first oldest girls of the ojamajo.

She is a decimal apprentice who works out very well with her magic just like Cute Decimal, the co-leader of the series.

Her sister is named "Tomiko", the unknown sister of "Miho" of the series, but they did not appear. They support her everytime when she did hard to her family at times.

Her absolutely most favorite best friend is Miracle Verbal, the former friend of Verbal Vowel, who likes decimals instead of verbs. They are paired together as "best friends" but, Verbal Vowel did not like her a bit.
