Nice Teehee Pero~ from our Suzuna pair in panel one

Illya is probably the smartest person in the room right now...

Suzuna Minami | Princess Connect Re:Dive Wiki | Fandom

She met Yuuki when she was having trouble calculating discounts while shopping, and finally Yuuki helped her calculate the discount on groceries she brought, after which Suzuna called Yuuki "Hidesai" (most likely Suzuna wanted to say "Shuusai" (talented) but misread the kanji),

• 秀: shuu
• 秀でる: hii-deru
• 才: sai

Well, to be fair to two of them, one is an amnesiac and the other one is an elementary school kid in real life despite her aspirations.

Suzuna though...
