Think kotatsu season is 'bout over.

Yes, Onii-sama.

I've left some senbei rice crackers in the kotatsu earlier. This removes the moisture, making them become crunchier and more delicious.

You oughtn't to, Young Miss! Don't rely on this thingamajig any further.

You'll reach the point o' no return.

The potato chips are crunchy too.

You have to cut ties as soon as possible...

Please, Miss! You should at least be the one to walk in the light...

Speaking about "walking in the light", you should really go out and get more sun. Original has Yakuza T first using an idiom about "walk on the path shined upon by the sun" (i.e. be a good girl and don't be a gangster like him) and then Cafe using it more literally as in "go out and get more sun."
