Previously:
Mother's Day
I decided to time skip here, using a random Father's Day about a decade (give or take a few years) post-Transition. The reason is I couldn't think of how to differentiate the two stories if it was just Kirito, Asuna, and Yui again.
I also decided that Kirito would probably want to
name his second daughter Sachi, even if he wasn't
Mister Seahorse at the time.
----------------------------------------------------------
"Sachi-chan! Wake up, Sachi-chan."
Sachi mumbled incomprehensibly as she opened her eyes, looking up at a familiar face, framed by long black hair. "Onee-chan? It's too early..."
"Finally," Yui smiled at her little sister, then disappeared out of view, "We have to get moving. The markets are opening, if we don't get there soon we won't get a shot at the best ingredients!"
Sachi snapped up, "Oh right! Today!"
"Right, today," Yui stepped back to the bed, "I've got some clothes for you. Get dressed and let's get going."
Yui and Sachi shot down the stairs, "We're heading to the market, Mama!" Yui called back into the house as the two sisters put their shoes on at the door. Asuna peeked into the hallway just as they were out the door, "Have a good trip, you two!"
Asuna started to leave the hallway after they shut the door, then stopped, "Ahh... she forgot it again..."
Asuna waited, counting softly in her head.
Three, two, one...
The door slammed open and Sachi stumbled through the entry, "I forgot it again!", hastily reaching for a small necklace hanging by the umbrellas. "Bye, Mama!"
A few short minutes later, Yui and Sachi floated down to the street just outside the Arrun market, Sachi hovering hesitantly just over the pavement. "Sachi-chan, you really need to get the hang of landing," Yui admonished, gently pulling her sister the last few centimeters to the ground.
Sachi mumbled her reply in embarrassment, prompting a grin from Yui, "You're going to have to soon, or you'll be the only one in school permanently stuck hovering over the floor..."
"Onee-chan!" Sachi protested, even as Yui guided her into the rapidly crowding market street.
The sisters slowly made their way down the street, stopping at several shops, picking up bread, tomatoes, lettuce, cheese, sliced beef...
"Onee-chan?" Sachi asked, through a bag piled high with groceries, "I don't think they charged us the right amount for all this."
Over her own full bag, Yui nodded, "Un. They know us very well," Yui explained, "But... the secret is, Mama doesn't accept any payment for the bottles of soy sauce she makes."
"Ah," Sachi said, "So they give us stuff in return, instead?"
"That's right." Yui confirmed. "Got a good hold on that bag?"
"Un." Sachi replied, and with a short hop she was hovering centimeters over the street again, and sliding slowly down it on excess momentum. Yui flew a few meters into the air and turned to watch her sister. With a bit of concentration, Sachi extended her wings, and in a moment was just beside Yui and the two sisters continued home.
The day grew brighter, and in a what seemed like a short time Yui and Sachi were in the air again, a wicker basket carried between them. This time, headed for Papa.
It was unfortunate Papa had to work. Caramella-san seemed to have a perverse humour in troubling Papa, and had asked him to
help out with this year's batch of mage trainees again. Luckily, the training grounds required neither secrecy nor great security. Still, a Sylph sentry hailed them as they approached the grounds.
"Yui-chan, Sachi-chan, good to see you today," the sentry greeted as the two floated down to the ground near him. "Still need the flight training charm, I see, Sachi-chan," he commented, his Sylph-granted sense for wind showing the subtle currents holding the younger girl stable.
Yui took the basket from her sister as they landed, allowing Sachi to slide along the ground on the anti-fall enchantments.
"Yeah. Though I think she'll manage to remember to grab it just in time to not need it any more." Yui walked quickly after Sachi, "Hold on Sachi-chan," but just as Yui reached her, Sachi pushed through the enchantment.
Despite stumbling from the effort, Sachi's face lit up with the accomplishment.
"That was pretty good!" Yui said, helping Sachi off the ground, "A little too much, though. Are you hurt?"
Sachi smiled, "No, I'm not hurt."
It didn't take long to find Papa. Yui hypothesized he could smell a sandwich from half a kilometer, and half again that if it was one of Mama's.
Sachi ran up to Kirito and hugged him tightly, Yui following shortly behind with the basket.
Looking up at her father, Sachi smiled, "Happy Father's Day, Papa."
