Welcome to Demon School, Iruma-kun - Videos

Some characters of Demon School and Hero Academia are VERY similar to the point the could be the same but in disguise.  Art style and character looks are similar as are the range and variety of appearances and skills.  The setting is very similar with a rather tough means I’d entry, after all like Midoriya both have no powers and are average humans, at least at first.

Both of these are shonen and school life anime. Plus the MC in both the series have kinda same personalities and looks.... They are also treated in the same way by the side characters. You'll also see the similarity in fact that deku character from MHA was in class A i.e. the top class with weird people and Iruma kun was in the abnormal class. That makes it more relatable. Some of the side characters are also similar in both. And both of them are really fun to watch.

i agree because both deku and iruma are having the same aura around them like all really kind and hardwrking and the plot line of the both of them going to school meeting new people but irum goes to not stand out and deku ges to school to become a hero

Both of these are stories about a normal person ending up at school in a magical world, but even amongst the plethora of anime with that exact plot, these are similar in that they are wholesome comedies. If you want more of the main character being kind and making friends, with the occasional season finale involving an actual antagonist, look no further.

they have a simular vibe, both main chacters want more from the llfe they had been living but dont seem to know how or what to do. only for it all to end up falling into place anyway mistly from the people around them.

Kind helpful main characters gained affection, make friends with everyone, accidentally created a harem no matter gender. Easy going, mostly heavy drama-free, just fun isekai time. 

Both remind me so much of each other. Vibrantly colored with very similar slapstick gag-type comedy (though I will say Nanbaka's jokes land better). Neither are spectacular by any means, but still good to watch after a long day when you just wanna chill and laugh a little. 

I saw people comparing this to Nanbaka, and though personally I can only see the comparison in terms of sparkly colour palette and quirkiness, Nanbaka is a much more entertaining anime.
