Suzumebachi wa Chiyukousei

On his way back home from a meetup with Daigo, Kazuma sees Hina at the park and as they talk, she collapses from hunger. Kazuma buys her some fast food and she explains that she has run away from home after her most recent fight with her father. Since she is without money or a change of clothing, Kazuma sneaks her into his room at Yorozuyo Inn. Senka discovers them the following morning but agrees to house Hina in exchange for housekeeping.
