CHIBI-QUE

Having gone through practices for sword mastery under the guidance of Jicchan,

Yui finally makes it and Jicchan is delighted with her growth.

However, when a monster suddenly comes, Jicchan protects Yui at the cost of his own life.

It clearly tells her that the demon lord has revived. In order to take revenge for Jicchan,

she sets out for an adventure to defeat the demon lord.
