Question about Overlord Laharl's high 4-C and 4-B

[Overlord775]

"At least Large Star level, likely Solar System level (Demons capable of destroying stars are considered "chump change" by Etna, whom he is stronger than, when she was far weaker than she is now; fought a veritable gang of such demons while severely weakened, and later an entire army of Human warships and personnel able to take them on) "

Ppretty sure that should be just 4-C and it's no way 4-B since the difference between 4-C and 4-B is 1200x

If I am remembering right the feat is from him busting every visible star in the night sky at the start of disgaea d2.

Edit: As well the line is more going about demons that can destroy multiple stars are chump change. This is backed up by the nether noble moster class. A nerfed disgaea1 laharl was able to beat members of the race with ease, one of the race's skills, Sand Wyrm Impact is stated by it's flavor text as "A powerful uppercut that can crush the stars." implying they can destroy multiple stars by just throwing an uppercut.
