Text score:

1) If you haven't already, watch season one and two of the anime KONOSUBA. Try to enjoy the show, despite it being a fairly silly isekai.   
2) Each individual ensemble member should prepare character introductions in the style and enthusiasm of the show's character Megumin or another Crimson Demon, for instance the character Yunyun (for additional reference beyond the first season watch the shows movie - Legend of Crimson).
3) As a minimum include each individual Current Resonance members personal ambitions for their future as artists.
4) Prepare appropriately dramatic background music.
5) The greetings should be prepared in Danish & Japanese. Pronounce it as correctly as possible. Use a machine translation if not confident in the language. Present the Danish versions first in the performance.   
6) The media/cultural context of the greetings should not be disclosed as part of the performance.
7) Incorporate the greetings in other parts of the performance, for instance at times when you're performing a 'special move', when interacting with audience members or similar. 

Read the mission statement of Current Resonance as a Gregorian chant.

Dress up and sing

let me nibble on your sleeve
let me hold the microphone
let me suck your lifeblood
as a community

Use this however you like
