系 group, tribe

It's ok to like 'visual KEI' if you are member of that tribe.

Everyone in the tribe is tied together with ONE string, making them ONE tribe.

xxx-tribe ★★★☆☆ PRE

SUFFIX meaning, belonging to the tribe of XXX. like 'visual kei' uses this kanji. Other common tribes, akiba-kei, furugi-kei (vintage clothes fanatics), and elvis-kei. I mean, probably.

of Japanese descent ★★☆☆☆
日 (sun, day) + 系 (group, tribe) = 日系 (of Japanese descent)

'of Japanese descent'. Nikkei American is Japanese American. But you can be nikkei Brazilian or nikkei Azerbaijani too!

solar system ★★☆☆☆
太陽 (the fucking sun!) + 系 (group, tribe) = 太陽系 (solar system)

systematic ☆☆☆☆☆
体 (body) + 系 (group, tribe) + 的 (motivation / '-al') = 体系的 (systematic)

systematic, and logical,like how dungeons and dragons takes all human attributes and assigns them a number.
