One great option is 'Fullmetal Alchemist: Brotherhood'. It has an amazing story that follows the Elric brothers on their journey to regain their bodies after a failed alchemical experiment. The character development is deep, and the plot is filled with twists and turns, exploring themes like sacrifice, redemption, and the consequences of playing god.
Another characteristic is that they can use fan service to enhance the mood or the character's personalities. In 'One Piece', Nami's outfits are sometimes a bit revealing, which can be seen as a form of fan service. But within the context of the story, it also shows her confident and sometimes cheeky personality. The overall story of the Straw Hat Pirates' adventures, their quests for treasure, and their battles against powerful enemies is so vast and engaging that the fan service becomes just one aspect among many that make the anime great.
'Food Wars! Shokugeki no Soma' also fits. The story is about a young chef named Soma trying to prove himself in a highly competitive culinary school. There is fan service in the form of the characters' over - the - top reactions to delicious food, which are sometimes depicted in a rather 'ecstatic' way. But the main focus remains on the amazing cooking battles and Soma's journey to become the best chef.
One of the best is 'High School DxD'. It has a great blend of fan - service and an interesting story about a high school student who gets involved with demons. There are a lot of scenes with attractive characters in alluring outfits and some comical yet engaging plotlines that keep viewers hooked.
Well, 'To Love - Ru' is quite famous for it. The story revolves around a high school boy who has to deal with a whole bunch of alien girls. There are lots of fan - service moments due to the nature of the alien girls' bodies and their interactions with the protagonist. It's a harem - type anime with a lot of comical and somewhat racy situations.
Another is 'High School DxD'. It's a supernatural anime. The story follows Issei Hyoudou, a perverted high school student who gets killed and then resurrected as a devil. There's a fair amount of fan service, but the plot also involves battles between different factions in the devil world, and Issei's growth as a character as he tries to become a powerful devil.
'My Hero Academia' can also be considered. While not as blatant as some others in terms of fan service, there are moments like the hero costumes which are cool and sometimes show off the characters' physiques a bit. The story, though, is amazing. It follows Izuku Midoriya's journey to become a great hero in a world full of people with superpowers, and it has great character development and a deep exploration of the concept of heroism.
Another characteristic is that the fan service can be used to add a bit of humor or spice to the anime. Take 'No Game No Life' for instance. There are some fan service - like moments, such as the outfits of the female characters. But the story is a complex and interesting one. It's set in a world where everything is decided by games, and the two main characters, Sora and Shiro, are trying to conquer this world through their gaming skills. The fan service doesn't overshadow the story but rather complements it in a way.
Another one is 'Your Lie in April'. It has a bittersweet romance. Kousei Arima is a piano prodigy who has lost his ability to hear the sound of his own playing after his mother's death. Then he meets Kaori Miyazono, a free - spirited violinist. Their relationship develops as they make music together. It's a story of love, growth, and the power of music with some really beautiful and uncensored emotional moments.
