Chika and Yumiko are to do more promos as Heart Tart. But before their first guest appearance, they get some nasty comments from Mekuru. Even worse, Yumiko has to admit that she has a lot to learn to get to Mekuru's level of skill and knowledge.
After all, I'm your big sis.
.فقبل كلّ شيء، أنا أختك الكبرى
Ich bin nämlich deine Onee-san.
Después de todo, soy tu hermana mayor.
Como si fuera tu hermana mayor.
Je suis ta grande sœur, après tout !
Perché io sono la tua sorellona.
Quero dizer, afinal sou
sua irmã mais velha.
В конце концов, я же твоя сестра.
