Kominesaki Ranko

The youngest sister of the Kominezaki family. The protagonist's underclassman.
A loli-debu type, with a body that's small, round and taut like a rubber ball. Eating is her side hobby. She refuses to do housework.

She initially resists the protagonist, keeping her attitude sharp and her heart closed off. As far as Ranko's concerned, men are "the enemy"-- thus, she rejects him without hesitation. Apparently this is due to something that happened in her past...

Even after being rejected so much, the protagonist still tries to get closer to her. Will Ranko open her heart to him...?
