yes, it's the Roderick family's insignia.

Hey! It's just the author's shameless review here, I just wanted to give a review since the book lacks one & also to provide briefing. There will be no harem, no plot armour, characters will be dynamic, multiple pov, multiple specializations, power system will be specific for each of them, not the generic reincarnation or transmigration in concept, MC won't be a loner though he will be selfish to an extent. MC will earn his strength and won't go 'courting death'. That's it for now.
