Aizen

A succinct and stylish Japanese name with an appealing and powerful meaning, Aizen can be interpreted as translating to "love and goodness", "lover of good", or "one whose good deeds come from love" — all qualities that parents may hope for in their children.

A name with spiritual significance too, Aizen forms part of the Japanese name for Rāgarāja, a Buddhist deity and Wisdom King, who could turn earthly lust into spiritual awakening. Known as Aizen Myō'ō in Japanese and Àirǎn Míngwáng in Sanskrit, his name translates to "love-strained wisdom king".

In popular culture, it may be familiar thanks to popular manga and anime series, Bleach, which features a character called Sousuke Aizen.
