Recently read graphic novels

Recently I've been reading a manga, which I am totally enjoying called Seto no Hanayome (translation: My Bride is a Mermaid). The plot is very unique and the story line is very crazy and humorous. The story is about a typical middle school boy named Nagasumi Michishio that goes to summer vacation with his parents to visit his grandmother living at the Seto Inland Sea. One day at the beach, he started drowning and when he was about to pass out, he saw the figure of a mermaid and suddenly woke up at a rocky shore. That night, while he and his family were passing their time normally, they had a sudden visit from a pretty girl named Sun Seto (and who's face Nagasumi recognized that were the same as the mysterious mermaid that saved him) that out of the blues asks Nagasumi to marry her, saying to take responsibility to what happened during the afternoon (which causes a big misunderstanding with his parents). Then a group of three suspicious men appear telling the family to accompany them to their base, saying that their boss/the girl's father would like to meet them, which the parents concluded to the situation that the girl is the daughter of a yakuza (mafia) leader. When the men escorted the family (with exception of the grandmother that was left alone) to a cliff by the sea, they where thrown to the sea and the men (which suddenly had fish tails) started pulling them to their base. At the base, they meet the girls parents which explains the situation of that if a merfolk's true form is suddenly seen by a human, the merfolk has to be executed. But there was a exception to the rule, that if the human were to merry into the merfolk's family, there was no need to worry about their secret since he/she are part of the group. Nagasumi later decides to take responsibility after noticing all of the efforts Sun was putting and all the risk she has taken because of him. The father is the the type that's super overprotective of his daughter and is totally against their marriage and is constantly in pursuit of taking Nagasumi's life. Soon, Sun decided move to Nagasumi's house at Saitama to prepare herself for her new life with him. From then on, thing gets crazy with: Sun's family suddenly taking over the school's faculty so they can watch over Sun. The appearance of Sun's childhood friend and famous pop idol Lunar Edomae, which almost brought the school to the brink of destruction all because of her petty rivalry towards Sun, and many more craziness later on. Also, I want to point out that the merfolks and other seafolks can change their form depending on the moisture of their body: when they're dry, they'll have legs or take human form/shape at most; and when they get wet with water, they'll turn to their true form from legs retuning to fish tails or others to turn back to the sea creature of their race (like a sardine, makarel, tuna, octopus, conch, shark, and orca [btw, this list does represent for some of the characters of the series]). The series also has a anime adaptation which already has a English dubbed version.
