Weakness and Charm
Kurosaki Ichigo could proudly say that he was strong enough to defeat hollows, arrancar, Espada, and any other bad guy who happened to have the nerve to threaten his loved ones.
However there was one weakness.
Yuzu glanced up at her big brother with her pleading eyes.
"Please Ichi-ni?" The Chappy plush she was holding gave off that 'cutesy smile' that reminded Ichigo of a doodle of Rukia's.
Ichigo could feel his resolve weakening, but he would not give in.
"Ichi-ni, don't you owe Yuzu 3,000 yen(1) for your Christmas gift?" Karin asked.
Minutes later, Ichigo was 3000 yen poorer.
An: Who can resist Yuzu's puppy eyes?
This had happened to me, by the charm of my own younger sister. Happy Holidays anyway.
(1) 3000 yen, by my mental math should equal to (roughly with allowance for error) about 30 U.S. dollars, But I'm not sure about the currency of other nations. Please correct me if I'm wrong.
