Similar powers and theme are presented in both series. Main character from both series have the power to see into the future. Their eyes glow too. MC friend in both series can use fire magic. The Red World is very similar to "The Ruined World". Only people who have special abilities can enter these worlds/dimensions.
Both involves the main character pulled into a world separate from their owns in which they must defend themselves with the new powers they've gained.
Both main protagonist has similar power in which they can briefly see an attack ahead of time before executed.
Both protagonist happens to bump into a girl, and without knowing much about them decided to help them. They soon travel and help protect the girl without much decision.
Both anime involves fighting and magical weapons/power, both girls use guns while the male protagonist uses a sword. If you enjoy magical fighting than you'll like these both.
Hitsugi no Chaika contains several elements found in Mahou Sensou - a magical war that took place prior to the start of the series, a girl with a gun that fires magic, a protagonist caught in a slightly odd love triangle, and multiple warring factions. However, Hitsugi no Chaika pulls them off far, far better than Mahou Sensou did and is a far better series overall.
Both involves, magical girl with guns who happens to bump into guy and his friend where their live where never the same again. the difference, the girl in one anime carries a pistol, while the girl in the other anime carries a big gun.
Both have magican, who is joining magic high school due magican appearence. Both give me similar romance feeling, even thought Mahou sensou doesn't have romance genre- main character is in love with his childhood friend.
The main characters had a normal life until a "magician" appeared. Both animes uses magic. Even though Mahou Sensou(Magical Warfare) does not have the "Romance" genre, it does have some love between them. Both has action genre.
Both shows are total dumpster fires in terms of plot - when watching them, you need to put you mind in neutral and just go with the flow.
But they are both fun to watch, and have a strong shonen romance element: A complete noob turns out to be super competent, and has tsundere girls in love with him, bu he doesn't have a clue.
It's pure escapist wish fulfillment.
The protagonist in both the series have serious hate relationship with a friend (in Arata) and brother (in Mahou Sensou). This was caused by a misunderstanding and it turned their relationship really bad. Also, in both series, the protagonist goes to a parallel world.
Both of these anime have fantasizing imagery of either demons and vampires or magicians and wizards. The main characters are joined upon by group of friends which are almost the same and have the same personalities. If you enjoy some romantic feeling, in school and magical explosion-action. This anime is for you!
+ Mostly just that the premises sound similar
+ Magicians fight against each other, and the main character only recently got caught up in this world because of the female lead
- The main characters have very different personalities
- Mahou Sensou isn't a battle royale-style war
- Both talking about "mahou wars",while in Mahou Shoujo Taisen is more comedy and relax,Mahou Sensou have a thoughtfull air in this plot;
- Both have almost the same title and what they mean too;
- Both have the use of magical objects and weapons and magic to defeat your enemies (In Mahou Shoujo Taisen the creatures and in Mahou Sensou others madoushis)
Three kids are invited to another world because they think their world is too boring. They are guided by a girl named kurousagi. Both Mahou Sensou and Mondaiji-tachi ga Isekai kara kuru sou desu yo? have "communities", and are trying to fight an evil force.
"Magical Boy" Genre
Cool Hero gets powers from Mysterious small black haired girl, ends up in situation where he must use his new found powers to save himself and said girl, brightly colored haired girl he knew from before also gets powers, though seemingly useless must be useful later on for something, cool friend also gets powers, siblings + family issues will probably be important later,
