Magical Girl Tear Shabon [Twinkle STARs]

Description:
Shadows are violent entities that appear when humans become mentally weak.
For some reason, there are no magical girls in charge of dealing with the Shadows in Hoshinozaka.

The protagonist, Iroha, becomes a magical girl by chance and is thus tasked with purifying the Shadows there.

She’ll face many challenges
— a bumbling group of delinquents, a mysterious black reaper…
Can she overcome them and uncover the dark conspiracy lurking in the town?
