The 'him' part is Kaminari- In this Jiro has an older sister named Nova. Her mum left for war and she won't see her for a while according to plan, so it's just her, Nova and her dad. Kyoka and Denki have been neighbors since childhood. Their mums have known each other as long as denki and kyoka known each other and both went to war together. Denki doesn't know his dad, so he's being watched by his nanny that's like, 4 years older than him and doesn't give a sh*t- They're (KamiJirou) 16 years of age, Nova being 18. EnJoYyY!!! P.S. I got this whole 'neighbor' idea from @jirouwu4820 that's their yt :) GO CHECK IT OUT!!!
