He was a Major in the Imperial Royal Guard and commander of the 16th Guard Battalion (Mana Tsukuyomi also belongs to this squadron) during the BETA Invasion of Japan in 1998, and has remained in that role even up to the Operation 21st on December 25th, 2001; in all of his appearances, Ikaruga has led his unit from the front, staying calm no matter the situation.

In Muv-Luv Alternative, Takeru wakes up three years after the end of Muv-Luv Unlimited to find himself back in his room. Although he first thinks that everything that had happened to him was a dream, he soon feels that something is wrong, and leaves the house to find that he has been sent back in time to the beginning of the events in Unlimited. Unwilling to accept something like Alternative V, he decides to help professor Kouzuki to complete Alternative IV and save mankind.
