Photon

Photon: The Idiot Adventures is a 6 episode anime OVA and manga series by Koji Masunari.

The main character, Photon Earth, is a young child who possesses superhuman strength, but is a bit simple-minded. While tracking down his childhood friend Aun Freya, who has stolen "the sacred artifact" (a marker) AGAIN, he gets lost and accidentally finds a crashed (space) ship. Made cranky by the fact that Aun ran off after he caught her, and by the fact that she wrote "Baka/Idiot" on his forehead while he was sleeping, he starts scribbling "Baka/Idiot" all over the walls of the ship in a rage.

Eventually he writes it on the forehead of Keyne Aqua (who was in stasis after escaping from Sir Papacharino Nanadan) and then falls asleep on her, because she reminds him of Aun's older sister (who took care of him when he was young -- but moved away after getting married). Neat little fact about marriage in that galaxy. Instead of giving each other rings, the guy will "claim" the girl by tattooing the symbol on his head onto hers. And guess whose doodling just activated the ship's wake-up routine?

Not to be confused with the live-action Sci Fi series of the same name, loosely based on the "other" laser tag franchise of The Eighties.

This show includes:

 * Accidental Marriage: When Photon, who had the word "Baka" drawn on his forehead by Aun, takes out his frustration by drawing it on an unconscious Keyne. Where Keyne comes from, drawing your partner's crest signifies marriage.
 * Accidental Pervert: When Keyne strips as she searches for the tracker Papacharino put on her, he starts to rise out of the floor and is accidentally treated to a "nice view" for a few seconds.
