I think Rezael would be a good adoptive father/father figure to Akina and Hikari. Unlike their actual father, who is away thanks to work, I can imagine Rezael will quickly come to them when he was informed about the incident, and comfort the crying Akina as he doesn’t want to lose him and Hikari like he did with Liael. The wholesome and heartfelt image of Him hugging the young, crying Akina is now etched into my brain now.
