In which episode did Kyouko gave the charm to Tsuna in Kateikyoushi Hitman Reborn?
The episode is Target 55: Resolution. At 17:45 she gives to Tsuna. YouTube
In case the video is deleted, below is the picture where she shows the charms she made for everyone.
I wanted to add a screenshot when she was giving charm to Tsuna, but I cannot find Tsuna, the charm and Kyouko all in a single picture.
