also: のふうぞ
noun
A somewhat old-fashioned or dialectal term for a mischievous person, often used affectionately. The exact nuance may vary by region.
あの野風増がまたいたずらをした。
That rascal has been up to mischief again.
A more common and neutral term for a mischievous child, while 野風増 is rarer and may carry a regional or old-fashioned flavor.
The origin is uncertain. It may be a dialectal or coined term, possibly from 野 (field) + 風 (wind/style) + 増 (increase), but the exact derivation is unclear.
