Akaha arriving for a visit one afternoon to explain to Kokoro about the inauguration party for the mayor Marie Momochi she attended with her mother Midori, tells the sisters of the Mayor's intention for a weekend visit. While Akaha and Kokoro speculate that the Mayor is inviting them to a party, Aruto and Iina suspect that it is for a far more sinister reason but support Kokoro's decision to welcome Marie with a sign the next morning only to find that Marie has a hostile political volition. Iina is surprisingly pragmatic about the whole situation later that evening as she defeats Kokoro's advertising proposal by stating the logistical obstacles of arriving at Kokoro Library. Iina and Aruto do not have to observe their sibling for very long to realize that Kokoro's anguish would eventually get the better of her. Aruto offering to write more novels as an income engine for the library becomes the preamble for Iina to again exhibit her insight regarding the big picture. Kokoro overhears her sisters' divergent concourse and races off to locate her father's diary that she hopes will save the Library.
