Abstract: A method may include setting, on the basis of an input by a player, a type of character among various types of characters as the character linked to the player. The method further includes commanding a display unit to display a progress indicator corresponding to the progress of a game. The method further includes accepting an input, by a player, corresponding to the progress indicator. The method further includes commanding a sound output unit to output narration voice that corresponds to the character set as linked to the player and that is related to the progress of the game.

Abstract: A soldering iron including an iron main body and an iron tip includes an iron tip main body having a hollow space inside extending along a longitudinal direction; an insulator tube in the hollow space; a heater wire to heat the iron tip main body, and a temperature sensor to detect a temperature of the leading end side of the iron tip, the heater wire includes: an outward route part extending towards a leading end of the iron tip, and a return route part extending towards a base end of the iron tip, while the heater wire folded back at a vicinity of the leading end of the iron tip being wound around the insulator tube, in the insulator tube, a heater wire hole to accommodate the return route part of the heater wire and a sensor wire hole to accommodate a sensor wire are formed independent of each other.
