To aid in her mission of observing Hana, Ruru transfers into her class under the name Ruru Amour, excelling in both studies and sports. Hana's family tries to hold Ruru a surprise welcoming party, but she seems disinterested, claiming there is no logical merit to it. Later, Hana goes searching for Ruru amidst an Oshimaida attack, unaware that she is the one who summoned it. When Ruru questions Hana over why she feels the need to look for her, she is taken aback when she tells her she wants to be her family.
