Zeno watches Kiriga tilt his head and squint his eyes. The 10-year-old purses his lips, seemingly biting them before giving in and glancing at the book opened on the table before him.

Kiriga gnashes his teeth as he reads over the correct fold and replicates it with determination. Kiriga measures with his eyes to make it even more precise in folding than the example piece Zeno had folded in a blink of an eye for the boy.

In 1845, Adachi Kazuyuki published a book which had more comprehensive compilation of paper folding. This book is called the Kayaragusa book, of which a copy laid right in front of Kiriga for the boy to learn from. Zeno smiles at the book, a piece of progress in slowly turning from the old Orikata to the modern origami.

Zeno lets out a hearty laugh when Kiriga brings his hand to his head to yank at his hair. The 10-year-old shakes his head in frustration once again. Kiriga looks at the opened page of the simplest origami that could be folded

A crane.

Now Kiriga could fold a crane all right but what was screwing him over was that Kiriga was trying to replicate Zeno. Zeno who had finished the crane faster than anything and didn't have to look at the book to remember which fold came next.

All in all Kiriga had yet to memorize the folds not to mention trying to do it with speed. Kiriga also seemed adamant about getting the exact measurements right.

Kiriga gnashes his teeth and crumples the -ruined in his opinion- crane and throws it to the corner where a pile of half folded paper had started to amount. He would have to either burn them for warmth or try to reuse them Zeno muses.

A small exclamation of joy has Zeno turning his attention back to Kiriga. Fumiko now stood at the opposite end of the table looking around the room. Her eyes lit up in excitement at the sight of Zeno's example crane.

The 8-year-old rushes to Zeno's side, eyes sparkling while her hand reaches for the crane. Zeno quickly grabs her tiny hand and pushes it down his voice already coming out with a scolding tone.

"Now now, don't touch the example crane Fumi, your brother needs it." Zeno pauses as the eyes previously lit in excitement mellowed out and became teary. Zeno quickly continued on to saying.

"If Miko wants a crane you can ask Zeno for one." And as Kiriga pouts at another ruined piece of paper Zeno adds as an afterthought. "Or make one yourself like Kiriga."

Fumiko's expression instantly improves. She sits herself to Zeno's left, opposite to Kiriga who was still concentrating on the exact placement of the next fold. Fumiko grabs one square sheet off the stack of prepared paper and then turns her gaze to Zeno expectantly as she holds it down on the table.

Zeno smiled lightly and gestures to the book. The younger Ubuyashiki's face doesn't sour but instead the excitement grows in her expression. She quickly turns the book around and away from Kiriga and reads through the open page. She reads the complex graph with ease, no furrow in her brow unlike her elder brother.

Kiriga glances up hastily when she snatches the book. The look of disbelief Kiriga displays makes Zeno giggle.

Fumiko ignores her brothers glare and instead proceeds on with the paper. She turns the paper around in different ways with her finger until a perfect little crane is ready.

Kiriga gawks at the crane. His eyes bulge at the small delicate thing Fumiko had made in less than 5 minutes. Fumiko is quite natural at this Zeno muses, while it may not be a strength of Kiriga. Kiriga still hasn't learned how to do it and it's been over 2 hours after all.

In an act of manly man dominance, the afro-mentioned 10-year-old boy throws the half completed crane in his hand at his little sister.
