Magical warriors! School students! Animal mascots! All three make up the similarities of both anime shows.
Both are about magical warriors who attend a school. In BinanLove, it takes place in a high school, while in Happiness Charge, it takes place in a middle school. Both leaders are young and more energetic than their teammates. Only difference is Megumi likes to help others and Yumoto likes animals.
Overall, just gender-swap the characters and this is your result.
