The resident otaku, Jun's main power as an Element is his "Mind Eye Photography" technique, which can enable him to see through solid objects and quickly target the weak points of enemies. He excels in handling computers and machines and although he rarely enters into battle, Jun spends most of the time operating the computers in DEAVA's control room. Jun was the first person Tsugumi met before getting in to DEAVA. She nearly ran him over but they soon became friends. Both him and Tsugumi can be a little naive but they mean well. Jun is very intelligent and can think fast on the battle field. Rena joked with him during a training exercise saying "You look nervous. Is this the first time you have held a girls hand?" Which he studiers at and replies "N-n-no. Of course not." And nervously takes her hand. It is also shown that he likes to cosplay. It is revealed at the end of episode 15, "Aquarion's first love", that he became addicted to merging just like Pierre but was not further explored.
