Remember the online poll on a replacement for Sento-kun? Rocking in Hakata caught the Asahi story announcing Sento's successor: Manto-kun.

Don.

Here's the Creators Yamato release, and here are Manto's designers, Kurogane Jinza.

What does "Manto" mean?

• It's Japanese for "cape" (from the French manteau, cognate with "mantle")
• It's a tortured but ultimately unrejectable way of pronouncing 万人, "10,000 people", i.e. "the myriad people", i.e. "everyone". The man here also suggests Man'yōshū_rc, as in the Nara-period poetry anthology. (Speaking of the MYS: Ancient wooden strip containing MYS poem identified!)
• Manto is also an obscure Sino-Japanese word written 満都 and meaning "the whole capital".
• Finally, Man to is an Edo-period adverbial meaning "in great quantities" (written 万と or 満と), but I don't think Nara recognizes that newfangled Edo slang as valid Japanese.
