From Storm in Heaven:

Saotome Masahiko is a plant fanatic who just transferred into his dream school, where he finds out that one of his classmates, Tendou Tasuku, is actually a highly-evolved plant. Tasuku is aloof and not exactly fond of humans, but can Masahiko's innocence win him over? Despite their differences, is it possible for super plants and humans to coexist side by side ...and even become... friends?

It was in the year 2800 of the Midgard calendar. Back then, there was a Overlord who once reigned supreme and had reached the very brink of subduing the world. Her name was Lufasu Mafaalu, a great woman dreaded as the Black-Winged Overlord. She was too strong, too fast, and too beautiful. However, she was defeated by Heroes who opposed her ferocity, and her ambition was brought to an end.

Or so went the story of our protagonist’s in-game character, whose body he now possesses for some reason in a world 200 years after Lufasu’s downfall. Follow our protagonist as he becomes unnecessarily feared by his surroundings and unnecessarily worshiped by his former subordinates as he―or now she―cheerfully travels around this fantasy world.

Arisue Sei lived as happily as any normal kid would, just him and his mother -- a particularly private woman -- on an outlying island of Okinawa. There were also his friends Toichi and Moichi. The only unusual things about Sei were his sharp instincts and high intelligence. But everything changed when his mother was killed and he was kidnapped by the people of Neo Genesis. Now, six years after the kidnapping, Arisue Sei has returned to Japan with the title of "Doctor" at only the age of 18, and he's not the Sei that his friends remember. There are bodyguards with him who protect him from others who wish to possess his superb intellect. He says he's come back to assist with the research at Rakuhoku University, where Moichi now works, but here is where the door to Sei's secrets just begins to open.

In a country very much like present-day Japan, governed by an emperor who rules with an iron fist, a dark disease known as "BT" is spreading out-of-control. All those infected with BT will be overtaken by an insatiable desire to kill.

The emperor charges a group of skilled men with the responsibility of eliminating all "BT carriers." Among them are two brothers with cursed blood running through their veins. Though they appear fearless, there is one thing even they seem to dread: the Yomizakura, a mark of death which serves as a chain binding them to their traumatic childhoods.

He meets a fellow school mate, Hatsuse Sakuno, on the way to Yashio and as soon as the two walk through the school gate, it's announced that he is the new student body president. As much as he tries to fight fate, he soon accepts the position of student body president on one condition: that Sakuno acts as co-president.
