(You roleplay as Raine Sage in this scenario)
Genis Sage is quite the work at times, mostly having the attitude in terms of scholarship and never the one to end arguments, he's by far pretty strong all things considered, using kendama, a ball type to chain his magic elemental spells into it for furthering the effects, effectively speaking, he's a menace in combat, having his strong suit in striking suddenly from afar and then continuing to push an advantage, as if he was playing football. But let it be no mistake, despite his positive outlook, there lies trauma beneath the surface, especially considering the fact that his parents passed away in a desperate attempt to save him, alongside his older sister, Raine Sage, now, she's the one acting like a mother figure to him, being one of the best healers, but lacking in cooking, it's not bad per say, but needs improvement. And since then, Genis Sage was constantly struggling with his emotional state, making himself excessive binges and constantly on the edge, to the point of sometimes acting too safe and cowardly at times, needing to being reassured by his sister most of the time. And such excessive eating would eventually lead to him gaining sizeable amounts of bulk, his frame being far rounder and plumper as a result, but still, deep down, he was very strong and self-assured, always finding positive in such changes, for instance, he started using his belly to bump kendama into enemies, alongside kicks.
You, Raine Sage, are the most efficient healer in all of Heimdall, to the point of constantly having to work with visitors of your homey place to ensure that no one leaves without proper treatment. Of course, you have to keep in mind about looking after your younger sibling, Genis Sage, but you didn't pay him much attention, due to how busy you were at everything. But one time, during one of many weekends, you approached the kitchen and were shocked at the sight, Genis Sage was stuck in the doorway, due to how much his waistline grew, how plump his stature was, at such a young age, only being 12, he weighed quite the stack and boy was it noticeable. As soon as you approached him from behind, he turned around and spoke, as much as his breath allowed him.
Well, I guess it's a sign that even my binges are too much, sorry for not checking it myself, I was just too engorged in it myself, all of my cooking was taste tested and ensured quality, since apparently you lack the knowledge and yes, everything led to this. Sis, could you push me out of the doorway please, I don't want to remain stuck.
Genis Sage was genuine with his confession about binging and all, but you had something in your mind that you couldn't quite put a finger on it, maybe you found his softened stature a sign of his maturity, that he didn't recognise it himself, but again, discussing it right now would be fruitless.
Will you be able to help him get out? Only mind matters.
