ermmmm wills u to write sm abt hsr x The Princess's Jewels with Bavilo trailblazer and junk >:] could be anything from head cannons to dum little things or lines idc
I will try but as I have said before, I actually do not know that much about HSR so it may not make sense.
-He and Stelle(I'm gonna keep her as part of the possible plot) met for the first time in the train and pent minutes looking at each other as they realized that if it wasn't for Bavilo's reddish eyes, they would be each other's copy.
-Wanting to create a line between who he is to his empire and his new adventure, Bavilo started using the name Caelus but when presenting himself he would say something like 'I'm Bavilo but please call me Caelus'
-He actually takes a bit of time to trust his companions and those they meet in their travels due to how he used to be treated before and that Ariana, Roserice, etc only treated him well to use him.
-He has a soft spot for Stelle and has adopted her as his baby sister.
-Kafka reminds him a bit of Benela but considers her a more truthful and nicer version of his mother
-He is easily surprised by the things he discovers about each new place and people he meets(Bavilo started writing about the things they discovered and has been encouraged by his friends to post it once they finish their travels)
-Bavilo cherishes each of the people he has met during his travels but Stelle, March 7th and Dan Heng are the ones he is closer to
-Even after he returned to the empire, Bavilo keeps in contact with those he met and at some point they all started to visit him often(and since they were all beautiful woman and attractove man, it attracted the attention of certain emperor and princess)
-He knows that some of the people he met on his travels have a crush on him but he was upfront about not thinking he is ready for a relationship but would gladly be their friend
-Bavilo returned to Arbezella in the ball Duke Krystell is humiliated by Ariana
-The Arzabella empire may act like they are the most powerful but that is simply in their planet because they aren't even in the top 50 of strongest empires in the universe
-The few times other royals have met Jaider, Roserice, Benela and Ariana they have immediately disliked them as their greed and lust were very noticeable
-Ariana is considered a persona non-grata in many planets after Bavilo informed their friends of her being looking for 'jewels' and how she treats her current jewels
-They were neutral to Bavilo as when they joined(or were forced to join) Ariana's harem, Bavilo still hadn't returned from his travels but got curious seeing how often unknown people visited him.
-Efrit was the first one to approach Bavilo to ask him for a spar as Efrit could immediately recognise that some who visited Bavilo were warriors so after their first spar, they start sparing quite often and a few of Bavilo's friends join them when they visit.
-Jade was the second one to approach Bavilo, hoping to find some solace and peace by Bavilo's side and he found that and a friend.
-Haun was the next one, seeing that he heard one of Bavilo's friends playing an instrument and also because Efrit had stopped antogonizing him since he befriended Bavilo
-Nell was the one after Haun, deciding that he needed to up his training and joined Efrit when he went to spar with Bavilo and his friends
-And Raymond was the last one, mostly due to his curiosity about what the other jewels found interesting in the least liked prince of Arzebella
-They all ended becoming friends with Bavilo and found themselves finding themselves better treated by him then Ariana and even heard about how harem members of other places were better treated then them(like they were treated equally and their opinion was asked before a new member was added to the harem) and maybe they found themselves falling in love with some of Bavilo's friends
