Honestly I really want Hoshi to just accidentally call Urahara "Dad"
Ask and ye shall Receive:
Sleeping at the Urahara Shoten was a common occurrence for Hoshiko, she was often there maybe once or twice a week, which meant that she was there in time for breakfast. The table, as always, was packed with foods and people. Jinta and Ururu sat on either side of Hoshiko, the three looking the part of sleepy children rather well. Jinta quietly ate his rice while Ururu stared at her cup of orange juice and Hoshiko put her hand out to reach for the bowl of fish.
Urahara handed it to her without a word, his other hand reaching for the tea.
“Thanks, dad.” Hoshiko said in the quiet of the breakfast table. She piled on two pieces of fish, putting the bowl down with a heavy clink. Wide-eyed, Urahara looked up, as did the others, all staring at Hoshiko who hadn’t even noticed what she said.
“Hoshi-neechan...” Ururu turned her slow gaze towards the girl, who looked over at her.
“Did you just...” Jinta continued, looking at her, wide-eyed.
“Call Urahara...”
“Dad?!” Urahara’s eyes lit up, “That’s so flattering, aw Hoshiko-chan, I love you too. You can call me dad whenever you want!”
“N-No! I di--I didn’t do that!” Hoshiko, now awake completely out of embarrassment vehemently denied, crossing her arms into an ‘X’ shape. “No!”
Needless to say, Urahara was in a good mood all day.
