Extreme: Shinobi Picture Scrolls

The is a collectable card game depicting several historical shinobi, which contains ten cards per packet and costs 30 ryō. Each card has a rarity level, some sort of stats, a picture along with a description and a village affiliation. Sometimes, the shinobi also has a special title, such as "Seventh Hokage". The cards are very popular amongst civilian and shinobi children alike, so much that some stores limit each customer to three purchases.

During his trip to Konohagakure, Tentō Madoka insisted on purchasing an entire store when told that he was limited to only three purchases. Boruto Uzumaki is shown to collect and add them to an album for safe keeping. Tentō also keeps his cards in an album and has bought so many that he has duplicates.

Trivia

 * In Boruto chapter 12, there are two blurred cards that resemble Kurenai Yūhi and Neji Hyūga.
