Sumika's Hyper is Reproduction of Records. When used, one copy each of the two most recent cards in the discard pile will be added to the player's hand. These copies will be treated as having no star cost and being Level 1 as long as they stay in the player's hand.
If Reproduction of Records is among the two most recent cards in the discard pile, they will be skipped and the next most recent card(s) will be copied instead.
Copies of cards with variable star costs will not have their star cost treated as 0.

Reproduction of Records can be used to copy powerful cards such asor and use them for free if timed properly. The Hyper, however, requires understanding how the discard pile works, and tracking discarded cards as well as used cards. The main problem with Reproduction of Records is that it relies on other players. If the user discards a card to try to copy it on the next chapter, the other players might discard or use cards to make the desired card not be copiable. Likewise, if the other players don't use any strong cards, the Hyper most likely won't make an impact on the game. The user also doesn't know what cards the opponent discards, so they might have no information on what is in the discard pile sometimes. However, some cards can provide the player with discard pile information such as and , as they let the player know what an opponent discards.
