Both anime have a guy being constantly cheered on by his friends (there's a reason). There's also romance in both of these.
A special group of people fight and get rid of demons, just like in Noragami. Even some scenes look very similar.
Both have the same genres of Music, School and Slice of life. The characters for both anime are cute and lovable. Both anime are also about a girl wanting to make a school club associated with music (idol/light music), but doesn't have enough members. Eventually, there are more members than the minimum.
The storylines for both anime are very similar. We have the main female lead, who's a tsundere and a male lead who isn't really in love with the female lead at first (in Nisekoi, Raku and Chitoge are in a fake relationship and in MKNR Makabe is trying to seduce Aki, while not having actual feelings for her). We also have the girl that comes out of nowhere and is in love with the male lead (Marika and Neko). Both anime are the Harem and romance type. There are a lot of similar situations played in both anime, too (I won't tell which, though, cause ykno, spoilers). Also, both anime end with a school play with a twist.
