Another Day, Another Song! Let's Go~
Nisekoi! (Nisekoi: False Love)
Click (Opening #1) by ClariS
What can I say, Nisekoi has one of the most catchy songs in anime. With this opening everything started where we got to meet the charming and colorful characters of Nisekoi. ClariS has released many songs like this for animes like "Mahou Shoujo Madoka★Magica" and "Ore no Imouto ga Konnani Kawaii Wake ga Nai" but the group got the most popularity with Nisekoi and with good reasons.
Step (Opening #2) by ClariS
The opening for the second half of the first season performed by the same group. However, this time they decided to go for a more emotional typical anime approach and even though is not as catchy as "Click", it fits the second half of the anime where a lot of characters have trouble controlling and understanding their emotions while still retaining that Nisekoi trademark and I love it!
Rally Go Round (Season 2 - Opening #1) by LiSA
Personally my definite favorite song in the entire anime. Not only is LiSA the goddess of anime rock but this song fits the anime better than any other. I mean Nisekoi is always full of romantic struggles but mostly full of comedy and action and all the aspects why Nisekoi is so enjoyable are shown through this one song. Maybe I'm biased because of my love for LiSA but you cannot deny the fact that her songs will always get you pumped.
1) Meirou by Kikuya Tomoki
The first video is hi-la-rious! I love any type of cute, charming and funny music. Meirou captures the style of Nisekoi's comedy, cheesy and complete weirdness, to absolute perfection. Everytime I listen to it I feel as if I should do something as weird as the characters. The style also gives you that European vibe and I haven't really heard anything like it in anime and I just can't get enough!
2) Summer Wind / Baka / Ribbon / Daydreaming by Kikuya Tomoki
Now, Meirou is indeed the funny side of Nisekoi but the songs in the second video shows us the emotional and charming side of it. I didn't really cared about who Tomoki was until I heard these songs. He has composed songs for many classic animes but he went and outdone himself with Nisekoi. I encourage you to listen to all of the soundtracks because these are some details that we don't really take into account unless you watch the anime twice and even then.
Heart Pattern (Ending #1) by Chitoge (Nao Touyama)
I never noticed (kinda knew) that the endings for the anime were sung by the characters themselves and the first one is by Chitoge. A song that portrays Chitoges random and curious behavior pretty accurately. Nao is the voice of Chitoge and you wouldn't believe how good she is in the industry. She has voiced characters like Caliburn (Ao no Exorcist), Chiho Sasaki (The Devil is a Part-timer), Yui (Oregairu) and so many more.
Recover Decoration (Ending #2) by Onodera (Kana Hanasawa)
The second ending for the first season sung by Onodera. Which also portrays Onoderas shy and charming personality very well. Kana voiced Onodera and she is another big figure in anime having voiced characters like Anri (Durarara!!), Sakura (Maid-Sama), Hana (Prison School) to name a few.
Aimai Hertz (Ending Season 2) by Chitoge, Onodera, Tsugumi & Marika
The 2nd season of Nisekoi has so many different endings but I picked this one as is pretty much the only one with the voice of so many of the characters, a song that has even the potential to be the opening of the anime to be honest and is the most used ending from the season. The titles for the other endings are: TrIGgER, Sleep Zzz, Matadō Rabu and marchen ticktack.
