Okay, so ‘Mob Psycho 100’ really got me thinking about family. The main character, Mob, is ridiculously powerful psychically, but all he wants is to be a normal kid and not have to use his powers all the time. It’s funny because his little brother, Ritsu, starts out being kinda jealous of Mob’s abilities, but Mob actually looks up to Ritsu for being so smart and socially adept. Their relationship is the heart of the show, honestly. They both have their own issues and insecurities, and watching them learn to accept each other – and themselves – is really powerful.

‘D.Gray-man’ (2006–2008)

Okay, so I’m totally hooked on ‘D.Gray-man,’ and one of the things I really love is the dynamic between Lenalee and her brother, Komui. She’s this incredibly strong Exorcist battling demons, but a lot of what drives her is protecting the people she cares about, especially Komui. He’s her supervisor at the Black Order, and he’s a bit of a worrywart – seriously overprotective, which is funny, but it comes from a real place. He feels terrible about getting her involved in this whole demon-fighting war. Honestly, their relationship is a bright spot in a really dark and gothic world. It feels like a little bit of home for Lenalee, and the show really highlights how those family connections are what give you the strength to face impossible odds. It’s a big theme throughout the series, and it’s done really well.

‘Haikyu!!’ (2014–2020)

Kei Tsukishima’s relationship with his older brother, Akiteru, is central to his personal growth in ‘Haikyu!!’.

‘Inuyasha’ (2000–2004)

As a huge ‘Inuyasha’ fan, one of the things I always loved was the complicated relationship between Inuyasha and his older brother, Sesshomaru. They’re both demons, but they constantly butt heads, especially over their dad’s swords and what it means to be strong. It’s not just simple sibling rivalry, though – there’s a lot of hurt and resentment from their past. They mostly fight, but sometimes they have to team up, and watching them slowly, painfully start to respect each other is a big part of what makes the series so good. It really makes you think about what family means and whether you’re defined by your blood or by who you are as a person.

In modern Kyoto, the four Shimogamo brothers—a family of tanuki—are trying to find their way after their father’s sudden death.
