## Description

The 'Before the Performance, Ruby' card serves as a key character entry in the 2024 Weiß Schwarz 【OSHI NO KO】 set. Identified by the card number OSK/S107-E014 and rated as a U rarity, this card is designed for collectors who appreciate the strategic depth and thematic elements of the 【OSHI NO KO】 franchise within the Weiß Schwarz trading card game. As a Character card, it belongs to the Show Business and Idol subtypes, offering specific gameplay interactions that appeal to both narrative-driven and competitive players.

In terms of gameplay mechanics, this card provides versatile support through its Backup ability. When utilized, it allows the player to select one of their own characters currently in battle, granting that character a protective ability until the end of the turn. Specifically, if the chosen character defeats an opponent in battle, that opponent is moved directly to the opponent's memory zone, effectively removing them from play for that phase. This mechanic supports aggressive strategies by helping to clear the board or secure advantages in combat.

Additionally, the card features an ACT ability that functions as a 【COUNTER】 with a Backup cost of 3000 power at Level 2. This effect requires the player to put the card from their hand into their waiting room, but in return, it grants +3000 power to a character being frontal attacked until the end of the turn. This makes it a valuable tool for stabilizing defenses or turning the tide of a critical battle. The flavor text, "You're not scared, Senpai?", adds a layer of narrative context to the character's persona.

For collectors, this card represents a tangible connection to the popular 【OSHI NO KO】 series. Its inclusion in the Weiß Schwarz ecosystem allows fans to engage with the story through gameplay, making it a desirable addition for those building decks or completing set collections. The U rarity designation indicates its availability within the set, balancing accessibility with collectibility. Whether for strategic gameplay or fandom appreciation, this card offers a distinct experience within the broader Weiß Schwarz landscape.
