Is this really Touhoku Kiritan, or is it just Youmu cosplaying as her?
Uploader here. The artist didn't added any cosplay or Youmu tags on Pixiv, so I don't think so. Besides, the artist is clearer when Youmu is making a cosplay of another character (See post #7496217 for example).
Is actually a local mascot character.Ah! They're teabagging!Education! Education! Education! Education! Death penalty! Death penalty! Death penalty! Death penalty! Death penalty! Death penalty!
In reference to the abusive language of the former Big Motor Vice President.5/11 is Local Mascot Characters Day!
Mascot characters promote the unique culture and local specialties of their regions or towns!
Wordplay from local (ご当地/gotouchi) where go = 5, tou = 10, and chi = 1.
